Type of Token. 

This depends on who generated the Token. Valid Types are:

• CLIE_TOKEN = '02' if generated by a Client (Student, Employee, ...),
• STAF_TOKEN = '03' if generated by a Client who is a Staff Member.

Note a token only uses CLIE_TOKEN. However, some function may flag STAF_TOKEN for Clients who are Staff Members.
