[pooma-dev] RFA: DomainIterator.h: Add DomainTraits Specializ ation

[James Crotinger]

Actually, will the problem be fixed if you include DomainTraits.h and
DomainTraits.int.h in Array.h and NewField/Field.h? These look like the
culprits - they define these ViewN structs, which make use of the
DomainTraits template, but the DomainTraits template and its specializations
are never included. Further, these are used to implement the generic
operator(), which is the main place where we need to detect if someone is
passing an int as an argument. 

(The general DomainTraits template is always included implicitly by the
client who uses a particular Domain, but the int specialization is not - I
don't know why this works with other compilers.)
