Prevent collisions between constructors

Additionally:
1) Add braces wherever possible for code clarity
2) Make all input coordinates const qualified
3) Remove not needed headers, and use c++ versions of needed headers
4) Fix typos
5) Comment out unused num_nodes parameters
6) Delete not implemented functions

Increment to version 1.3.

Removing VerdictFunction typedef from verdict.h, since its no longer true that all verdict functions have the same signature.
Now that c++ is required, one can use std::function, lambdas, etc... instead.

Remove extern "C" from all functions.
With
namespace verdict {
  extern "C" void func();
}
the result is functions are decorated in code (requiring one to type "verdict::") but not decorated in the resulting binary.

Reintroduce mangling support by allowing the user to set the name of the namespace.
