    PySimpleGUI Demo Program Browser

    Originaly written for PySimpleGUI Demo Programs, but expanded to
    be a general purpose tool. Enable Advanced Mode in settings for more fun
    
    Use to filter and search your source code tree.
        Then run or edit your files

    Filter the list of :
        * Search using filename
        * Searching within the programs' source code (like grep)
    
    The basic file operations are
        * Edit a file in your editor
        * Run a file
        * Filter file list
        * Search in files
        * Run a regular expression search on all files
        * Display the matching line in a file
    
    Additional operations
        * Edit this file in editor
        
    Keeps a "history" of the previously chosen folders to easy switching between projects

    # Grep reads a *ton* of files into memory then searches through the memory to find the string or regex/pattern corresponding to the file.

    # memory mapping (mmap).
