CRUD Development

(No Jira Story associated with issue yet):  Updated MySQL object to (1)
generate datetime and append to (currently fixed) tenant ID for use as
PCR ID in database, (2) check user permissions in order to determine
schema current user is bound to (assumes tenancy is supported via
separate schemas, method maybe needs revision), and (3) returns the
created PCR ID after insertion so client can access record in the
future.  Multiple tests performed on CRUD and Login services with
multiple users and incorrectly formatted forms simultaneously to locate
errors or other areas in need of revision.
