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.

{{#Invoke:Coordinates | dec2ch1903 }} : Simple function for converting decimal
degree values to CH1903 format.

{{#Invoke:Coordinates | dms2ch1903 }} : Simple function for converting DMS format
to CH1903 format.

{{#Invoke:Coordinates | dec2utm }} : Simple function for converting decimal
degree values to UTM format.

{{#Invoke:Coordinates | dms2utm }} : Simple function for converting DMS format
to UTM format.

{{#Invoke:Coordinates | link }} : Export the link used to reach the tools

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}}.
