Package diffmatchpatch offers robust algorithms to perform the operations required for synchronizing plain text.
package diffmatchpatch

DiffMatchPatch holds the configuration for diff-match-patch operations.
Number of seconds to map a diff before giving up (0 for infinity).
Cost of an empty edit operation in terms of edit characters.
How far to search for a match (0 = exact location, 1000+ = broad match). A match this many characters away from the expected location will add 1.0 to the score (0.0 is a perfect match).
When deleting a large block of text (over ~64 characters), how close do the contents have to be to match the expected contents. (0.0 = perfection, 1.0 = very loose). Note that MatchThreshold controls how closely the end points of a delete need to match.
Chunk size for context length.
The number of bits in an int.
At what point is no match declared (0.0 = perfection, 1.0 = very loose).
	MatchThreshold float64
}
New creates a new DiffMatchPatch object with default parameters.
