--[[
This module is intended to replace the functionality of {{Coord}} and related
templates.  It provides several methods, including

{{#Invoke:Coordinates | coord }} : General function formatting and displaying
coordinate values.

{{#Invoke:Coordinates | dec2dms }} : Simple function for converting decimal
degree values to DMS format.

{{#Invoke:Coordinates | dms2dec }} : Simple function for converting DMS format
to decimal degree format.

dec2dms

Wrapper to allow templates to call dec2dms directly.

Usage:
    {{ Invoke:Coordinates | dec2dms | decimal_coordinate | positive_suffix | 
        negative_suffix | precision }}
    
decimal_coordinate is converted to DMS format.  If positive, the positive_suffix
is appended (typical N or E), if negative, the negative suffix is appended.  The
specified precision is one of 'D', 'DM', or 'DMS' to specify the level of detail
to use.

dms2dec

Wrapper to allow templates to call dms2dec directly.

Usage:
    {{ Invoke:Coordinates | dms2dec | direction_flag | degrees | 
        minutes | seconds }}
    
Converts DMS values specified as degrees, minutes, seconds too decimal format.
direction_flag is one of N, S, E, W, and determines whether the output is 
positive (i.e. N and E) or negative (i.e. S and W).

coord

Main entry point for Lua function to replace {{coord}}

Usage:
    {{ Invoke:Coordinates | coord }}
    {{ Invoke:Coordinates | coord | lat | long }}
    {{ Invoke:Coordinates | coord | lat | lat_flag | long | long_flag }}
    ...
    
    Refer to {{coord}} documentation page for many additional parameters and 
    configuration options.
    
Note: This function provides the visual display elements of {{coord}}.  In
order to load coordinates into the database, the {{#coordinates:}} parser 
function must also be called, this is done automatically in the Lua
version of {{coord}}.
