 * 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 your code--
 | 
						|
 *   TOC("A name", 5);
 | 
						|
 * }
 | 
						|
 *
 | 
						|
 * Is the correct usage for multiple TIC() / TOC() calls.
 | 
						|
 *
 | 
						|
 * TIC() / TOC() creates its own block, so make sure not the mangle
 | 
						|
 *  it with another block.
 | 
						|
 *
 | 
						|
 * The output is counted in CPU cycles, and not comparable across
 | 
						|
 *  machines. Mainly useful for local optimisations.
