+query for heart rate samples. the options object is used to setup a query to retrieve relevant samples.
+```javascript
+let options = {
+    unit: 'bpm',										// optional; default 'bpm'
+    startDate: (new Date(2016,4,27)).toISOString(),		// required
+	endDate: (new Date()).toISOString(),				// optional; default now

+the callback function will be called with a `samples` array containing objects with *value*, *startDate*, and *endDate* fields
+
+*example usage*
+```javascript
