Evolve the empy templates to applications

[francocipollone]

Summary

Nowadays we are using empy templates to obtain xodr descriptions.

Proposal

We could embed the empy interpreter in python applications

Take a look at http://www.alcyone.com/software/empy/#Embedding-Empy

        import em
        interpreter = em.Interpreter()
        # The following prints the results to stdout:
        interpreter.string("@{x = 123}@x\n")
        # This expands to the same thing, but puts the results as a
        # string in the variable result:
        result = interpreter.expand("@{x = 123}@x\n")
        # This just prints the value of x directly:
        print interpreter.globals['x']
        # Process an actual file (and output to stdout):
        interpreter.file(open('/path/to/some/file'))
        interpreter.shutdown() # this is important; see below

Benefits

• Create xodr file and geojson files
• Easier to receive arguments instead of using environment variables
• Creation of python modules that are shared among the templates
