 * 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).
