[rules-dev] Instantiating class with no constructor

[Mark Proctor]

I chatted to jason and he recommended a multi strategy.
1) weaving on startup (i.e. injecting no argument constructors) if you 
own the AS
2) using Sub14RefletionProvider if you are on a VM that supports it, 
several do
3) finding equivalents to above if you are different vm
4) resorting to what we do now, where users much impl no arg constructor 
themselves.
