 * @name       MeshMap - a dynamic map for the mesh network

 * @version    $Id$

 * @abstract   Eric has written a tool called get-map-info which retrieves HAM Mesh network devices,
 *                     their configuration and Linkage information. These details are populated in several SQL tables.
 *                     The map.php routine extracts the DB details and creates a dynamic map of those nodes and links.
 *
 *             The primary display tools are:
 *             Map Drawing by Leaflet http://leafletjs.com
 *             Map data by OpenStreetMap http://openstreetmap.org

/* Current version notes
 * 
 * March 2018
 * wow, it's been that long huh?
 * now using git repo at https://mapping.kg6wxc.net/git/meshmap
 * fixed issues with running the webpage on PHP 7.2.3, it should be good now.
 * tested on PHP 5.6.30 7.0.27-0+deb9u1 and 7.2.3
 * had to create an array properly and not let PHP fix my mistakes for me. :)
 * more to come!
 *
 * June 2017
 * -----------------
 * Added CSS values
 * First pass at Optimization for Node and Topology array handling
 * Moved several control values to user-setting.ini
 *                       Including: Server Settings, Messages, Starting Coordinates and Zoom
 * GSE: Moved map specific details to meshmap-settings.inif
 * GSE: Optimized link building
 * GSE: Cloned map.php to map_display.php for additional ( non-mesh ) features
 * GSE: Moved Icon and Colour definitions to meshmap-settings.ini
 * GSE: Moved all map building infrastruures to individual routines.
 * GSE: Added ( Additional Markers ) - These are additional filtered non-mesh markers.
 * GSE: Added Services to the mesh node pop up
 * GSE: Added Popup to Link lines.
 * GSE: Added another popup for those nodes with an non-standard firmware version. ( Visiable when layer is active )

/* Historical Notes ( colapsed )
* early march 2017
* -----------------
* sorted "Linked to:" popup list by distance and cost
* this was easiest by putting the distance info into the database.
* see the scripts for more info
* Can now tell the difference between "real" DTD links and those that are linked in some other way (mostly)
* Additionally, This page is becoming more and more modified to do things based on which "host" it is running on
* At SBARC we currently have 3 different "versions" of this page, plus my system I use for testing
* I was starting to lose track of what was where so it has all become one now.
* if you are running on a different host then things will default to "normal".
*
* early feb 2017
* -----------------
* changed to use only free (as in beer) maps
* OSM, openTopo, Stamen maps, etc.

* early jan 2017
* -----------------
* migrated to use mysqli
* also added the mapbox "topographic" maps (which suck)

* mid dec 2016
* -----------------
* yet another update (due to request)
* added distance and bearing info to the linked node listing in the station popup

* more updates dec 2016
* -----------------
* added lat, lon to the popup info
* added channel and bandwidth info to the station popups
* out of date (and maybe beta) firmware now shows up as red text in the station popups
* changed the bottom "attributions" section a bit, formatted it differently and added in the number of stations and links shown. :)

* v.03 early December 2016
* -----------------
* added fullscreen control.(mid november 2016).
* the basemap layers are now able to be switched.
* there is differentiation between the different bands.
* now more info in the stations popup.
* you can now filter out different bands and different types of links on the map.
* the node's name now shows up if you hover over the marker.
* I think I'm now able to pick out the tunnels vs. any other type of link... maybe
*
* v.02 early Nov 2016
* -----------------
* new "radio" icons
*  "two way" link lines
*  legend overlay
*
*  v.01 inital map Oct 2016
* -----------------
