Message:

• Added a NXgetrawinfo function in the internal section. This function does not do any special processing for strings and rather returns the raw data size as read from file for strings. This is a special for Paul Kienzle. I marked this function as internal becuase for all normal cases, NXgetinfo as is does the right thing. Refs #173 We may even consider supressing documentation for NXgetrawinfo.
