leaflet-spatial-prefix-tree's Issues

upgrade bootstrap and jquery

Tested and was fine, with:

<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js"></script>

The leafletJs need some study, not so easy to upgrade.

Actually make it a plugin

It's not actually a 'plugin', more of a demo.. if someone wants to pluginify it, I'd be happy to merge the PR.

Openning the map with a Geohash defining the location

I included the javascript below in the index.html and is working fine (!). Try to navigate with index.html#6gycfqf0 or index.html#geohash:6gycfqf0 with this javascript:

<script>
var hash = window.location.hash
hash = hash.replace('#','');
if (hash) {
	// check prefixes "geohash:" (default) or "quadtree:" or "slippy:"
	var prefix = ['geohash','quadtree','slippy'];
	var selected = 'geohash';
	var pos = hash.indexOf(':');
	if (pos != -1) {
		selected = hash.substr(0, pos)
		if (prefix.indexOf(selected) == -1) 
                     alert("HASH ERROR: no known "+selected);
 		hash = hash.substr(pos+1)
        }
	alert("OK, we can see the map at \n"+hash);	
}
</script>

To continue: how to change by javascript the map location?

PS: if we can translate a Geohash code and the position of the map by Javascript, we can display map by the URL-supplied Geohash.

Hi, there are a way to use something like
