//If our version of the standard library suports shared pointers then we can use that implementation, otherwise

//Ironically 'typedef templates' are coming in the next version of C++, by which time we won't need them.

//In some ways these integer types are an implementation detail and should be in the PolyVoxImpl namespace.
//However, we will be passing them into and out of PolyVox functions which are seen by the user, and we'd
//rather not have to use the PolyVoxImpl qualifier, espessially as it will show up in Doxygen. This is just a
//temporary work around until it's properly supported by C++ anyway...
