/**
 * GEO my WP Map class
 *
 * This class handles some features that use Google Maps API such as generating a map,
 * address autocomplete, Directions and more.
 *
 * All maps generated by this class ( via GEO my WP or its extensions ) collected into the $map_elements array
 * and sent to the map script ( JavaScript file ).
 *
 * The map script then loops through the collection of maps and generates each map.
 *
 * It is possible to control almost every feature of the map by passing the desired arguments
 * to the get_map_args() and get_map_element() functions.
 *
 * Usually, to generate a map you first need to use the get_map_element() function
 * to generate the map element on the page in the desired location.
 *
 * Then you need to use the get_map_elements() function when you have all the arguments ready.
 *
 * For example, when generating Posts Locator map you need to use get_map_element() after the loop,
 * when you have all the locations that needs to be displayed ready to pass to the map.
 *
 * enqueue_scripts is "attached" to the footer using wp_footer action and will enqueue only the required
 * JS files based on the map arguments.
 *
 * This way we don't enqueue JS files that are not being used.
