Suggestion of descriptive text for Code2FN in e2e jupyter notebook for OpenHouse demo

[Clayton T. Morrison]

<text>

The Code2FN service take code as input (in multiple different forms), runs the program analysis pipeline to parse the files into CAST and translate the CAST into a Function Network (FN) and returns Gromet Function Network Module Collection (GrometFNModuleCollection) JSON.

The service currently accepts Python and Fortran (family) source code. The language type is determined by the filename extensions:

• Python: .py
• Fortran: .f, for, f95

The service can accept the following four types of code forms:

• string containing code
• single file
• multi-file - array of text-blobs and corresponding filenames
• zip archive containing a directory tree of source code files

@vincentraymond-ua :

• Can you verify that my list of supported Fortran extensions is accurate and complete?
• Does my description of the input types look correct?
