105-Python - Directory File Search & Verify

This routine is the skeleton for searching directories for files (wild cards * and ? allowed) and verifying a file exists before opening it for read.

This is part of a folder (a little library) of small bits of tested code that work. Things like file I/O, interrupts, GPIO definitions, print examples, etc. I don't have to re-invent the wheel every time I write a program. I can go to that folder, copy the pieces I need and be done with my program quickly and with less thrashing.
