* This class can compare two different versions of a text. Source refers to
* the earliest version of the text and target refers to a modified version of
* source. Changes are considered either as a removal from the source or as an
* addition to the target. This class detects changes to an entire line and also
* detects changes within lines, such as, removal or addition of characters.
* Take a look at DiffTest to see the expected inputs and outputs.
