+  This is a standalone deserialize/parse example if you just want to deserialize
+  thrift decoupled from cassandra server
+
+  1.  acquire thrift template specification files from who ever built it (eg: EXAMPLE.thrift)
+
+  2.  Install thrift on local machine (ie, via "brew install thrift")
+
+  3.  generate thrift clients for nodejs using template specification files (#1)
+      thrift --gen js:node schema/EXAMPLE.thrift
+
+      This creates creates gen-node.js directory containing a new file, GENERATED.js
+
+  4.  Inside GENERATED.js is a class you will want to instanciate.  Find this class name and plug 
+      it into the example code below  (ie, "YOUR_CLASS_NAME")
