Instance Variables can now be scanned and parsed
Ivars: read and asign

We can now read from and assign to IVars using the @foo syntax.
Method defination implimented

In the context of a class, Foo, `def bar(a,b)` will new create a function and
place that function in the cvars of Foo under bar.  This in tern results
in bar being a method for instances of class Foo.
