11:01 am Colony Revision 1602: Added some test files for fixed point math.
Something definitely broke in cosine when I changed to smaller tables
(which shouldn't have sacrificed any accuracy)...

Lazy implementations of sine and tangent (that just
use cosine indirectly).
Addressed edge cases.
Needs EXTENSIVE t...

06:02 pm Colony Revision 1579: Initial pass at a 32-bit fixed point library.
- Generated cosine / sine tables, put them in PROGMEM
- Wrote initial quadratic interpolation cosine function.
