-         * converts the patterns to a (typed, if possible) array as described by Liang:
-         *
-         * 1. Create the CharMap: an alphabet of used character codes mapped to an int (e.g. a: "97" -> 0)
-         *    This map is bidirectional:
-         *    charMap.code2int is an object with charCodes as keys and corresponging ints as values
-         *    charMao.int2code is an array of charCodes at int indizes
-         *    the length of charMao.int2code is equal the length of the alphabet
-         *
-         * 2. Create a ValueStore: (typed) array that holds "values", i.e. the digits extracted from the patterns
-         *    The first value starts at index 1 (since the trie is initialized with zeroes, starting at 0 would create errors)
-         *    Each value starts with its length at index i, actual values are stored in i + n where n < length
-         *    Trailing 0 are not stored. So pattern values like e.g. "010200" will become […,4,0,1,0,2,…]
-         *    The ValueStore-Object manages handling of indizes automatically. Use ValueStore.add(p) to add a running value.
-         *    Use ValueStore.finalize() when the last value of a pattern is added. It will set the length and return the starting index of the pattern.
-         *    To prevent doubles we could temporarly store the values in a object {value: startIndex} and only add new values,
-         *    but this object deoptimizes very fast (new hidden map for each entry); here we gain speed and pay memory
-         *    
-         * 3. Create and zero initialize a (typed) array to store the trie. The trie uses two slots for each entry/node:
-         *    i: a link to another position in the array or -1 if the pattern ends here or more rows have to be added.
-         *    i + 1: a link to a value in the ValueStore or 0 if there's no value for the path to this node.
-         *    Although the array is one-dimensional it can be described as an array of "rows",
-         *    where each "row" is an array of length trieRowLength (see below).
-         *    The first entry of this "row" represents the first character of the alphabet, the second a possible link to value store,
-         *    the third represents the second character of the alphabet and so on…
-         *
-         * 4. Initialize trieRowLength (length of the alphabet * 2)
-         *
-         * 5. Now we apply extract to each pattern collection (patterns of the same length are collected and concatenated to one string)
-         *    extract goes through these pattern collections char by char and adds them either to the ValueStore (if they are digits) or
-         *    to the trie (adding more "rows" if necessary, i.e. if the last link pointed to -1).
-         *    So the first "row" holds all starting characters, where the subsequent rows hold the characters that follow the
-         *    character that link to this row. Therefor the array is dense at the beginning and very sparse at the end.

- * jQuery.ScrollTo
- * Copyright (c) 2007-2009 Ariel Flesler - aflesler(at)gmail(dot)com | http://flesler.blogspot.com
- * Dual licensed under MIT and GPL.
- * Date: 5/25/2009
- *
- * @projectDescription Easy element scrolling using jQuery.
- * http://flesler.blogspot.com/2007/10/jqueryscrollto.html
- * Works with jQuery +1.2.6. Tested on FF 2/3, IE 6/7/8, Opera 9.5/6, Safari 3, Chrome 1 on WinXP.
- *
- * @author Ariel Flesler
- * @version 1.4.2
- *
- * @id jQuery.scrollTo
- * @id jQuery.fn.scrollTo
- * @param {String, Number, DOMElement, jQuery, Object} target Where to scroll the matched elements.
- *	  The different options for target are:
- *		- A number position (will be applied to all axes).
- *		- A string position ('44', '100px', '+=90', etc ) will be applied to all axes
- *		- A jQuery/DOM element ( logically, child of the element to scroll )
- *		- A string selector, that will be relative to the element to scroll ( 'li:eq(2)', etc )
- *		- A hash { top:x, left:y }, x and y can be any kind of number/string like above.
-*		- A percentage of the container's dimension/s, for example: 50% to go to the middle.
- *		- The string 'max' for go-to-end. 
- * @param {Number} duration The OVERALL length of the animation, this argument can be the settings object instead.
- * @param {Object,Function} settings Optional set of settings or the onAfter callback.
- *	 @option {String} axis Which axis must be scrolled, use 'x', 'y', 'xy' or 'yx'.
- *	 @option {Number} duration The OVERALL length of the animation.
- *	 @option {String} easing The easing method for the animation.
- *	 @option {Boolean} margin If true, the margin of the target element will be deducted from the final position.
- *	 @option {Object, Number} offset Add/deduct from the end position. One number for both axes or { top:x, left:y }.
- *	 @option {Object, Number} over Add/deduct the height/width multiplied by 'over', can be { top:x, left:y } when using both axes.
- *	 @option {Boolean} queue If true, and both axis are given, the 2nd axis will only be animated after the first one ends.
- *	 @option {Function} onAfter Function to be called after the scrolling ends. 
- *	 @option {Function} onAfterFirst If queuing is activated, this function will be called after the first scrolling ends.
- * @return {jQuery} Returns the same jQuery object, for chaining.
- *
- * @desc Scroll to a fixed position
- * @example $('div').scrollTo( 340 );
- *
- * @desc Scroll relatively to the actual position
- * @example $('div').scrollTo( '+=340px', { axis:'y' } );
- *
- * @dec Scroll using a selector (relative to the scrolled element)
- * @example $('div').scrollTo( 'p.paragraph:eq(2)', 500, { easing:'swing', queue:true, axis:'xy' } );
- *
- * @ Scroll to a DOM element (same for jQuery object)
- * @example var second_child = document.getElementById('container').firstChild.nextSibling;
- *			$('#container').scrollTo( second_child, { duration:500, axis:'x', onAfter:function(){
- *				alert('scrolled!!');																   
- *			}});
- *
- * @desc Scroll on both axes, to different values
- * @example $('div').scrollTo( { top: 300, left:'+=200' }, { axis:'xy', offset:-20 } );

- Copyright 2011, Kovid Goyal <kovid@kovidgoyal.net>
- Released under the GPLv3 License
- Based on code originally written by Peter Sorotkin
- http://code.google.com/p/epub-revision/source/browse/trunk/src/samples/cfi/epubcfi.js
-
- Improvements with respect to that code:
- 1. Works on all browsers (WebKit, Firefox and IE >= 9)
- 2. Works for content in elements that are scrollable (i.e. have their own scrollbars)
- 3. Much more comprehensive testing/error handling
- 4. Properly encodes/decodes assertions
- 5. Handles points in the padding of elements consistently
- 6. Has a utility method to calculate the CFI for the current viewport position robustly
-
- To check if this script is compatible with the current browser, call
- window.cfi.is_compatible() it will throw an exception if not compatible.
-
- Tested on: Firefox 9, IE 9, Chromium 16, Qt WebKit 2.1

-    ###
-    This class is a namespace to expose CFI functions via the window.cfi
-    object. The most important functions are:
-
-    is_compatible(): Throws an error if the browser is not compatible with
-                     this script
-
-    at(x, y): Maps a point to a CFI, if possible
-    at_current(): Returns the CFI corresponding to the current viewport scroll location
-
-    scroll_to(cfi): which scrolls the browser to a point corresponding to the
-                    given cfi, and returns the x and y co-ordinates of the point.
