Functions for scenrio export for automated testing.

[2qx]

The code to evaluate scenarios lives in the BitAuth project, but the following functions would be very handy to have in libauth for automated testing of libauth templates.

• a function to generate a list of passing/failing scenarios from a template
• a function to generate/validate individual scenario transactions from a template.

Ideally, anyone could easily map template scenarios into a list of unit tests for a template.
