This class exists because there is no notion of a "virtual constructor" in C++. In particular, it is used in ProcBlockManager::ProcBlockManager() to create a map which lets you take a string and construct a particular processor. The usage in that class is:

procAllocators["daq"]= new ProcAllocatorTmpl<DAQProc>;
procAllocators["singlepe"]= new ProcAllocatorTmpl<SinglePEProc>;
// etc, etc...

And later, it can then create an instance of FrontEndProc by
doing this:

proc = (*procAllocators[procname])();

If this does not quite make sense, don't worry, you probably don't
need this class.

@param  T  Processor class instantiated by this factory.  Must be
           subclass of Processor.
