fixed indent typo in model.py, edited some styling
experimenting with differ
separate additions and deletions in differ
switching to context_diff
added nltk to parse sentences, using regex to access data in context_diffs
pulls line numbers from context_diff
Can regenerate text for one diff hunk, but not multiple
stores multiple diff hunks in array, but line numbers not aligned after 2nd+ hunk change so regenerated text is not accurate
