-    Version 1.1

-    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

-

-    TODO

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