Basic graph diffing

[shiftre]

Create a basic graph diffing either by constructing our own graph or using IDA's.

Classic examples would be Levenstein and Hamming distance but I think we could do better, specifically because we could extract hot areas (APIs, loops, other features we've already done).

There are two types of graphs, one is a function's graph (the one i think you're talking about - graph of connections between function basic blocks), and another which is the graph of relationships between functions in an IDB.
Both should yield decent results.
