* Text diff implementation.
*
* This library supports the following APIS:
* JsDiff.diffChars: Character by character diff
* JsDiff.diffWords: Word (as defined by \b regex) diff which ignores whitespace
* JsDiff.diffLines: Line based diff
*
* JsDiff.diffCss: Diff targeted at CSS content
*
* These methods are based on the implementation proposed in
* "An O(ND) Difference Algorithm and its Variations" (Myers, 1986).
