Generate Python Functions from Rune

Feature Request - Generate Python Functions from Rune

Description of Problem:

The generator does not have the capability to create Python from Rune defined functions. This limits the usability of the generated code when the model includes function definitions. In these cases, the definitions are just ignored but this can be an issue if the model leverages a function in a Type's condition.

Potential Solutions:

Refactor the generator to create Python code for function definitions leveraging any changes made to the runtime (see Rune Python Runtime Issue #13)
