Added Two Other Modules
Added Decimal-Fraction Integration

Variables are now defined as a dictionary, with parts currently:

'mode' for whether it is a fraction or decimal
'decimal' for the decimal value of a number
'numerator' for the numerator of a number
'denominator' for the denominator of a number

When a variable is recalled, the value of it is given based on what
mode it is in.
Added mode() Function

mode(var, fractionOrDecimal) is a simple, temporary function to change
the mode of a variable to either fraction or decimal.
