Detailed Description

View1<Object,Domain>::Type_t is defined for several Pooma objects, and tells you the type of a(b).

You should be able to write code like:

 A a;
 B b;
 typename View1<A,B>::Type_t c = a(b);
 

ViewN will also give the type for the read() member function in arrays and fields.

To define the view properties for a new class, you should specialize View for that class. Reliance on the partial specialization ordering rules for more than one argument is a very bad thing, so never define View for a particular domain and general A. (It will be common for us to define View for general domains with a particular A, so specializations with general A would also require complete specializations in order to avoid ambiguity.)
