something like it eventually.
Args are fairly straight forward.

int ybase: location of "left" edge of battery on screen
int len: how long is the battery to be (in pixels)
int wid: how tall is the battery to be (in pixels)
int percent: what percentage of the charge has been used
Note: I am making use of the Logf() function until logging is
straightened out.
