typical usage:
//create analysis
DiffMatchPatchComparator dmpc = new DiffMatchPatchComparator();
Analysis analysis = dmpc.compare(s1, s2);
//format into HTML
AnalysisHTMLConverter converter = new AnalysisHTMLConverter();
converter.setAnalysis(analysis);
//left = original, right = other
String left = converter.getLeft();
String right = converter.getRight();
