template<class T>
class PxReportCallback

Base class for callback reporting an unknown number of items to users.

This can be used as-is and customized by users, or several pre-designed callbacks can be used instead (see below).

This design lets users decide how to retrieve the results of a query:

• either one by one via a regular callback

• or one batch at a time via a callback

• or written out directly to their own C-style buffer

• or pushed back to their own PxArray

• etc
