* Refactored all files to have Interfaces within the same file. Started moving over to file-scoped namespaces. * Refactored common methods for getting underlying file's cover, pages, and extracting into 1 interface. * More refactoring around removing dependence on explicit filetype testing for getting information. * Code is buildable, tests are broken. Huge refactor (not completed) which makes most of DirectoryService testable with a mock filesystem (and thus the services that utilize it). * Finished porting DirectoryService to use mocked filesystem implementation. * Added a null check * Added a null check * Finished all unit tests for DirectoryService. * Some misc cleanup on the code * Fixed up some bugs from refactoring scan loop. * Implemented CleanupService testing and refactored more of DirectoryService to be non-static. Fixed a bug where cover file cleanup wasn't properly finding files due to a regex bug. * Fixed an issue in CleanupBackup() where we weren't properly selecting database files older than 30 days. Finished CleanupService Tests. * Refactored Flatten and RemoveNonImages to directory service to allow CacheService to be testable. * Finally have CacheService tested. Rewrote GetCachedPagePath() to be much more straightforward & performant. * Updated DefaultParserTests.cs to contain all existing tests and follow new test layout format. * All tests fixed up
