/**
* The CoordInfoFormatterHandler manages CoordInfoFormatters for all of the
* CoordMouseModes, in order to provide a consistent coordinate display across
* mouse modes that display coordinate info. If you want different coordinate
* information for each CoordMouseMode, set the CoordInfoFormatter on each mouse
* mode and don't use this class in the openmap.components property or
* MapHandler. Only use this if you want to provide a choice to your users and
* you want that choice used over all of your mouse modes.
* <P>
* This class should be placed in the MapHandler, which you can do via the
* properties by adding it's marker name to the openmap.components property
* list. The properties look like this (for a marker name coordFormatterHandler):
*
