* Unneccesary Operation Removed
(A) extra operation not needed and incorrect:
wrong by 0.5 but happens to be thrown out
( delta * dividend + (divisor / 2) ) / divisor
delta * dividend divisor
= ---------------- + -----------
divisor 2 * divisor
= delta * dividend / divisor + 1/2
(B) check first before doing other computations
(C) changed to rise/run, easier for future maintainer
since it's closer to equation of a line
(D) before: mult, shift, add, div, add
now: mult, div, add
(E) error message easier to trace where thrown
* Update WMath.cpp
forgot to change variable name
* fix typo in WiFiMulti
* clean up trailing spaces
* clean up script file used in cleaning
