Integration between STK and BoM Analytics

[Andy-Grigg]

There needs to be some interop between STK objects and this package, but we don't want to use the heavyweight STK objects directly.

Implement a lightweight coupling between the STK and this package in the form of python dicts / JSON string.

Some other thoughts:

• Some sort of decorator that checks argument type?
• Avoid isinstance, can we do something with dict or slots?

[Andy-Grigg]

This is implemented as much as possible from the PyAnsys side, in that a dict of GUIDs and DBKeys can be provided when building a query. Will require a more coordinated effort between this package and STK to do something more joined up.

[Andy-Grigg]

Some thought needs to be given to how we set a non-standard db key and tables in this package.
