From dd78a1d02fd1071a0a88e72a9add51795a9d0d28 Mon Sep 17 00:00:00 2001
From: Tom Joseph <tomjoseph@in.ibm.com>
Date: Fri, 5 May 2017 11:04:29 +0530
Subject: Write parser for inventory to sensor mapping yaml.

Write python-based parser for inventory-sensor.yaml.
The parser generates inventory-sensor-gen.cpp, which is contains a map
containing the inventory object path as key and the sensor related info
as the value.
