Summary:
Parameter maptemplate don't work
Detailed Description:
From CGGoogleMaps help:
"(optional) maptemplate="" - Specify the name of an existing, non default map
template to use for this output. If this parameter is not specified, the current
default map template will be used"
This parameter is not working because in source code it is only declared but
never used for db query.
CGGM_PREF_DFLTMAP_TEMPLATE (default template) is the only working template.
