[Bf-python] Hashing Vectors

[Campbell Barton]

Hi, There are a few scripts I have that I use a dict for vertex 
locations, so as not to double up on locations as an example

vert_dict[tuple(vertex.co)]= vertex.index

It would be nicer and faster if the 2,3, or 4  floats could be hashed, 
any hints as to hashing a vector and possibly a matrix type?
