Wait function that uses 16 Bit Timer 1 instead of using 32 bit Timer 0 to be used in conjunction with 'TextLCD16x4_Wait' and 'PulseWidthCapture' to measure the +ve and -ve Pulsewdth of a signal
Dependents: PulseWidthCapture_Program

+/***********************************************************************************************************************
+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.
