Lua Module for Utility Functions

wordinal: Word-Ordinal form of number Parameters: 1 = Number (0-99) Return: Ordinal in Word form of number "??" for 0 or non-numeric input Input number for number >= 100

ordinal: Ordinal Numbers Parameters: 1 = Number 2 = Cardinal (return cardinal number if true) Return: Ordinal Number (Or simply number if cardinal is true) it does not seem logical to have an ordinal function return cardinal numbers, but it saves 'Ifs' in the calling module --]=]
