Move stringtodriver utility used in tests to main silo library

Nobody has claimed this yet.

The tests have the ability to manipulate the HDF5 driver in many details using some special code there to convert a command line argument string to a Driver id specification. However, that should really be moved to the main library so anyone using Silo can take advantage of it.

Description:
The tests have the ability to manipulate the HDF5 driver in many details using some special code there to convert a command line argument string to a Driver id specification. However, that should really be moved to the main library so anyone using Silo can take advantage of it.

Comments:

Start by locating the test code that converts command-line strings to HDF5 driver ID specifications, then trace how the main Silo library exposes driver functionality. Move that utility into the public library area so Silo users can access it, and verify that the existing tests still manipulate drivers successfully.
