Log:
Simplify CriteriaBuilder by moving the actual criterial logic to
exprssionSignature(), leaving just the binding-management and 
meta-function support in the class.  This simplifies some things
for meta-function compilers, since they only have to deal with one
kind of builder now, and they can use expressionSignature to convert
their arguments into conditions instead of expressions, if needed.

(This should also make it easier to implement an @expand_as decorator 
for even simpler, compiler-free meta-functions!)
