* 1 - other non-fatal, non-severe warnings
* 2 - crude progress indicator of functionality
* 3 - important debugging messages (function entry)
* 4 - debugging messages (crude loop status, etc.)

* Usage:
* TIC();
* --Do your code--
* TOC("A name", 1);
*
* When you run the TIC() / TOC() multiple times, you can increase the '1'
* to only display average stats every N values. Some things to know:
*
* for (int i = 0; i < 5; i++) {
* TIC();
* --Do yuor code--
* TOC("A name", 5);
* }
*
* Is the correct usage for multiple TIC() / TOC() calls.
*
* TIC() / TOC() creates it's own block, so make sure not the mangle
* it with another block.
