Enhanced the one-time secure token, through the use of an HTTP header passed in all requests. Now, client and ottoken are not passed on the command line or in parameters, cleaning up the authorization checking.

Added a Database connection pool to more cleanly handle multiple parallel request without blowing out the database or memory.

Added a new client/requester to simplify client calls

Reworked tests for new client and for nonce header
Reworked the documentation to match the new Requester client and HTTP header for one time secure token
