* Function: void LCDUpdate(void)
*
* PreCondition: LCDInit() must have been called once
*
* Input: LCDText[]
*
* Output: None
*
* Side Effects: None
*
* Overview: Copies the contents of the local LCDText[] array into the
* LCD's internal display buffer. Null terminators in
* LCDText[] terminate the current line, so strings may be
* printed directly to LCDText[].
*
* Note: None
