ability to handle application source when more than 1 source file is present

[atinsood]

Objective

Currently the application source tab shows the source code of the python file that was used. but for more complex projects there will be more than 1 python source file.

Proposed implementation

Rather than rendering the file, we should leverage the kui tree renderer to render the location of the folder containing the file. that ways the user can browse through any other files in that folder structure .

Architecture needed: How do we elaborate transitive python code imports from an index.md, where all of the assets have to be inlined into that index.md.
