+/*********************************************************************************************************************** 
+This library has been created to create a new wait function that uses the 16 bit Timer 1 rather that the traditional 32 Bit Timer 0.
+This library is intended for use with the 'TextLCD_16x4' Library to get the lcd to work alongside the 'PulseWidthCapture' Program.
