Create tests for the itbp.py program

[Alan-R]

Here are a few things to verify in the tests

• that it scrubs its input before looking at files - avoid the equivalent of SQL injection - no data leakage from the server
• that it produces a few classes of correct results - fully qualified, partially qualified, best practice id only
• that it fails on a few cases, where partially qualified would work, but fully qualified would not, where data is invalid, etc
• others of your choosing ;-)

Do you want to consider the idea that the JSON to be returned might be malformed?

It is highly desirable that these tests should be possible to run without being root.
