[E-Lang] Coming Attractions: Java Overload Resolution

In Elmer,

? integer maker protocols

return s a bunch of gobbledygook that includes:

#        }`, "new(int, Random)/2" => e`to new p0, p1 {

which presumably is the one you want.

? help(integer maker)

however, only returns

# value: "an org.erights.e.elib.prim.EStaticWrapper\n\
#        ONE/0
#        ZERO/0
#        asType/0
#        new/1
#        new/2
#        new/3

which tells you nothing about the argument.  Let me suggest enhancing help 
to show arguments, and in the case of overloadings that will not be 
automatically selected, something suggestive of the precise string that 
must be provided to "call".
