Our current setup for custom hashing objects to to give them a method .getHash() which looks like this:

T.prototype.getHash = function () {
  var someSubsetOfT = // code here
  return ve.getHash( someSubsetOfT );
}

and to invoke we use

 ve.getHash( instanceOfT );

However ve.getHash( instanceOfT ) === ve.getHash( ve.getHash( someSubsetOfT ) )
which isn't really what we want.

One solution would be to rename getHash to getHashableObject (or something) and have it return just someSubsetOfT directly.
