/**
 * Change the way gmap works.
 *
 * @param $op
 *   The operation to be performed. Possible values:
 *   - "macro": Add macro behaviors (Not well documented yet...)
 *   - "pre_theme_map": A map is being themed. This is a good place to
 *     drupal_add_js() any additional files needed to run the map in question.
 *   - "macro_multiple": Add macro behaviors (Not well documented yet...)
 *   - "behaviors": Define behavior flags used in your code.
 * @param $map
 *   For the "pre_theme_map" operation, the map being themed. Not used in
 *   other operations.
 * @return
 *  This varies depending on the operation.
 *  - "macro": An associative array. The keys are the macro keys, the values
 *    are an array of flags for that macro key:
 *      "multiple": This key can appear multiple times in a macro.
 *  - "pre_theme_map": None.
 *  - "macro_multiple": An array of macro keys that can appear multiple times.
 *    (Oops, this appears to be redundant... Look into this. --Bdragon)
 *  - "behaviors": An associative array. The keys are the names of the behavior
 *    flags, and the values are associative arrays in the following format:
 *      - "title": The title to show on the settings page.
 *      - "default": The default state of the flag.
 *      - "help": A description of the flag to show on the settings page.
 *      - "internal": If TRUE, the flag will be marked as map specific, and
 *        will not be stored in the defaults.
