+Minimal client

+Below is a minimal template client to quickly get started. Mirrors the python example above.
+This example will:
+
+* create a bucket
+* insert an event
+* fetch an event from an aw-server bucket
+* delete the bucket again

+Reference client
+----------------

+Below is a example of a watcher with more in-depth comments. Mirrors the python example above.
+This example will describe how to:
+* create buckets
+* send events by heartbeats
+* insert events without heartbeats
+* do synchronous as well as asyncronous requests
