#10 initial Angular 1.5 code

I verified this code works in a very basic Angular app.  In it, my main html page included all the needed JavaScript libraries.

leafletSolrAngularComponent.js

+
+using the leaflet-solr-heatmap library in Angular 1.5
+
+we must tell Angular about our component
+this example uses the variable leafletSolrComponentOptions which is declared below
+
+<script>
+    angular.module("myapp", [])
+	.component('leafletSolrComponent', leafletSolrComponentOptions)
+        .controller("HelloController", function($scope) {
+            $scope.helloTo = {};
+            $scope.helloTo.title = "AngularJS";
+         });
+</script>
+
+
+to add a leaflet map and heatmap layer to a web page, we declare a leaflet-solr-component tag as follows:
+
+<leaflet-solr-component the-title='theTitle' mapdivid='map' solr-url='http://localhost:8983/solr/jstorTest' 
+       options='{"field": "bbox_srpt", "nearbyField": "bbox_bbox", "popupDisplay": ["doi","title"],"type": "heatmap"}'>
+</leaflet-solr-component>

+
+// the component wrapper around the leaflet-solr-heatmap JavaScript library
+// leafletSolrComponentOptions should be passed to the .component function as illustrated above
+// not that I have little experience with Angular
+var map;
+var leafletSolrComponentOptions = 
+{
+    bindings: {theTitle: '@', mapdivid: '@', solrUrl: '@', options: '@'},

+	 console.log('theTitle', this.theTitle);
+	 map = L.map(this.mapdivid).setView([0, 0], 1);
+
