Renamed the support_vectors field of the decision_function and distance_function objects · eff11e27

Davis King authored Nov 29, 2009

to basis_vectors.  A long time ago the name support_vectors made sense but now that these
objects are used by a lot of algorithms that don't technically produce support vectors
this name is confusing.  The name basis_vectors more accurately reflects how these objects
get used.
