This plugin uses the devices native mapping functionality to show a list of locations
on map. Locations are markers with a title and sub-title. An optional icon can be
included for each location that loads another screen or shows driving directions when
it's tapped. The control panel allows other advanced adjustments to control the maps
behavior and features.

The list of locations on the map may be individually entered in the control panel or
may come from a remote file. If you're showing more than a dozen or so locations it's
best to use a remote file to supply the location data.

iOS Project
------------------------
4 Objective-C classes (a total of 8 files) are needed.
BT_screen_map.m and .h
BT_mapAnnotation.m and .h
BT_mapZoomLevel.m and .h
BT_mapAnnotationView.m and .h

BT_screen_map.m is the main UIViewController that shows the map. The other classes are
used to produce the individual locations and handle view options and interactivity.

Android Project
------------------------

AN ADJUSTMENT NEED TO BE MADE TO YOUR PROJECT AFTER YOU DOWNLOAD YOUR CODE
BEFORE YOU CAN USE MAPS IN ANDROID

Before the map will work you'll need to obtain two Google Maps API keys for Google Maps.
One is called a Debug key and one a Release key. These do not cost
money but do confuse lots of people. It's easy once you get the hang of it.

Instructions on how to get the API keys are here:

BT_screen_map.java is the Activity class that displays the map. The layout is handled by
screen_map.xml. Additionally, several graphic files are needed to show the locations on the map.

Version History
-----------------
v1.3     03/11/2015     iOS, no changes.
                         Android.
                         
                         --Updated code for Android Studio. Android Studio references the
                         Google Map libraries a bit different than Eclipse did and the map code
                         needed small changes to accomodate for this.
                         
                         --Added support to remember the "pan / zoom" position on the map when
                         coming "back" to the map after tapping a details button.
                         
                         --Add support for Share Screenshot. The setting "allowShareScreenshot" allows

JSON Data
------------------------

If you manually enter the location data, the JSON data for this item in the BT_config.txt
includes a child items array holding individual map locations like this....

{
     "itemId":"1111",
     "itemType":"BT_screen_map",
     "itemNickname":"Location Map",
     "navBarTitleText":"Monterey Spots",
     "childItems":[
          {
               "itemId":"loc_1",
               "itemType":"BT_locationItem",
               "title":"Cool Restaurant",
               "subTitle":"1234 Elm Street Anytown CA",
               "latitude":"38.4323",
               "longitude":"-121.2345"
          },
          {
               "itemId":"loc_2",
               "itemType":"BT_locationItem",
               "title":"Another Restaurant",
               "subTitle":"1234 Main Street Anytown CA",
               "latitude":"38.4223",
               "longitude":"-121.5645"
          }
     ]
}

If you provide location data from a remote file there is not childItems array. Instead,
the locations are pulled from a remote file then added to the map.

{
     "itemId":"1111",
     "itemType":"BT_screen_map",
     "itemNickname":"Location Map",
     "navBarTitleText":"Monterey Spots",
     "dataURL":"http://mywebsite.com/locationsForMap.php"
}
     
In this case the locations would come from a backend script at the dataURL. Loading
the dataURL in your browser would produce output like this....

{
     "childItems":[
          {
               "itemId":"D441703507867F328A084DF",
               "itemType":"BT_mapLocation",
               "latitude":"36.600723",
               "longitude":"-121.8928338",
               "title":"Location 1",
               "subTitle":"234 Del Monte Blvd Monterey CA 93940"
          },
          {
               "itemId":"419993F0FEC3312C797C91E",
               "itemType":"BT_mapLocation",
               "latitude":"36.615763",
               "longitude":"-121.904234",
               "title":"Location 2",
               "subTitle":"801 Lighthouse Ave Monterey CA 93940"
          },
          {
               "itemId":"11F25D4F6120F19E7F4B220",
               "itemType":"BT_mapLocation",
               "latitude":"36.5977439",
               "longitude":"-121.8949035",
               "title":"Location 3",
               "subTitle":"823 Alvarado St Monterey CA 93940"
          }
     ]
