    blaconvert - Java program for converting units of measurement and currency using Google APIs

    based on code by  Joe Robinson <joe@lc8n.com>
    
    Version 1.31
    
    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 support for currency symbols
    1.31 - Trying to add euro (probably won't work)
    TODO
    - Raw output option - result only with no spaces/commas/units
