Angles have their own system that define both radians and degrees.  I would
like to create the necessary type for minutes (this is 1/60 of a degree).
 My first thought was to create a scale unit with degrees as the base type.
 I couldn't determine how to enter the scale of 1/60.  The other option is
to define a new base unit.  I would think using the degrees base unit would
be a good reference, but it uses an "INTERNAL ONLY" macro call
"BOOST_UNITS_DEFINE_BASE_UNIT_WITH_CONVERSIONS".  What should I use to
create a unit type that will convert from degree minutes to just degrees?
