Changes to all parts of the project:

• Size optimizations.
• Added a define (EXCLUDE_FROM_XTIDECFG) to exclude unused library code from XTIDECFG.
• Tried to minimize time spent with interrupts disabled.
• Some minor attempts to improve speed (reordering instructions etc).
• Tried to improve readability, did some cleanup and fixed some errors in comments.

File:

• trunk/Assembly_Library/Src/Util/Math.asm (modified) (3 diffs)
