Function Name: CamInt_resetCam
Function Description: This function is responsible
for resetting the camera. This is accomplished by
toggling the reset line on the OV6620 for ~100 mS.
Inputs: none
Outputs: none
IMPORTANT NOTE: This function has effectively been removed
since resetting the camera now causes the camera to not
output the clock signal. Thus, if we reset the cam, the
AVR has no clock, and thus doesn't run...
