17 /* Debugging messages policy:
18 * These should be the severities used for direct DEBUG() calls
19 * maximum debugging level should be 10 if really deep, deep
20 * debugging is needed.
21 * (there is room for exceptions, but you have to have a good cause):
22 * 0 - errors or severe warnings
23 * 1 - other non-fatal, non-severe warnings
24 * 2 - crude progress indicator of functionality
25 * 3 - important debugging messages (function entry)
26 * 4 - debugging messages (crude loop status, etc.)
27 * 5 - detailed debugging information
28 * 6.. - extremely detailed spamming

72 * Usage:
73 * TIC();
74 * --Do your code--
75 * TOC("A name", 1);
76 *
77 * When you run the TIC() / TOC() multiple times, you can increase the '1'
78 * to only display average stats every N values. Some things to know:
79 *
80 * for (int i = 0; i < 5; i++) {
81 * TIC();
82 * --Do your code--
83 * TOC("A name", 5);
84 * }
85 *
86 * Is the correct usage for multiple TIC() / TOC() calls.
87 *
88 * TIC() / TOC() creates its own block, so make sure not the mangle
89 * it with another block.
