=head1 DESCRIPTION

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)

This module 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.  Note that special characters 
or non-numerical characters such as " will throw an warning and return NaN for that list item. 

In addition, the input does not interpert N,S,W,E designators but expects coordinates to be in 
positive or negative representation. 

Format of the output can be controlled via input arguments in the constructor. The arguments are expected 
to be in the form of a hash reference. For example:

	# Change output format
	# Hash aruements are 
	# 'dd_fmt' = Decimal-Degrees format
