first basic version of LPA_INT divide - doesn't handle the -ve case at the end of the loop
needs a lot of optimisation work
minor tweaking
fixed bug with carry on multiply
tested single divide
new test function */ to some tests for divide using multi-digit numbers
still only tests single digit divide
need to extend test functions to do multi-digit division
added LPA_BCD_toHexadecimalASCII function
added LPA_INT_toDecimalASCII function
tests for LPA_INT_toDecimalASCII() and LPA_BCD_toHexadecimalASCII()
