minor bug with EXP as NOSET and variable initialization
Updated vector reads of vme_analyze to be more generic.

The problem is that sol_mpa saves a specific vector component (eg bx) of multiple probes into one file.

Other routines (eg. hall) save multiple components into a file.

The current method of reading in a vector autoassumes the first approach.  The program has been generalized
to also work with the second approach.
