    Version 1.3
    
    CHANGELOG
    1.0 - First version
    1.1 - Allow units with more than one word eg "light year"
        - Added "same unit" error
        - Ensure standard imperial measurements are used for some units - google defaults to US
    1.2 - Replace crazy non unicode spaces with commas
    1.21 - Added quart to imperial measurements
    1.3 - Added csupport for currency symbols

    TODO
    - Raw output option - result only with no spaces/commas/units
