/*TODO:
Change:
Indx
- newCmd
+ _newCmd
_MAXCMDLENGTH
move the global variables to a class because we arent paeasents - Mission Failed
use jack's motor motor position
fix class variable naming
dont make everything public becuase thats fucling dumb and defeats the whole point of a class
+
+Move things out of public and into a protected part of the class
+
+Move char Comm::_inCharQ[] = {'.','.','... into the class by making it a vector
+
+Change abs lacro to
+NOT V0 but R0 (to go on forever)
+
+Actually make the code robust lol
