Transform latitude/longitude between coordinate functions

 There are several formats used to present geographic coordinates. For
 example:
 .
  * DMS Degrees:Minutes:Seconds (48 30 30, -117 30' 30")
 .
  * DM Degrees:Decimal-Minutes (48 30.5, -117 30.5'),
 .
  * DD Decimal-Degrees (48.5083333, -17.5083333)
 .
 Geo::Coordinates::Transform converts a list of provided latitude and
 longitude coordinates in any of the three formats above (mixed input is ok)
 and converts to the desired format.
