[Cpprest] Generated client code does not handle arrays of primitive types, integers with min and max values, or API methods that return a file properly.

[sdrichter]

Description

When generating a cpprest client using a YAML/JSON API specification that uses arrays made up of primitive types (in my case integers), the cpprest code generated has multiple errors with std::vector that prevent compilation. The generated code is invalid due to some errors in the mustache files for cpprest that result in invalid C++ code being generated for this case.

Another issue is that when using integers with min/max values, the generated client code attempts to set the default value of the integer to nullptr, which is invalid.

Finally, API methods that return a file object are not handled correctly in the generated client code.

Suggest a Fix

I am very close to resolving these issues on my fork of swagger-codegen.

I have modified several of the mustache files for cpprest as well as the code generator java. There were logic errors in the mustache files related to the isPrimitiveType check. I will issue a pull request once I have fully tested my changed. I wanted to get the issue logged here so everyone was aware I am working on it.
