+""" Class defines the interface for Direct inelastic reduction with properties 
     present in Instrument_Properties.xml file
+
+    The class is written to provide the following functionality. 
+
+    1) Properties are initiated from Instrument_Properties.xml file as defaults. 
+    2) Attempt to access property, not present in this file throws. 
+    3) Attempt to create property not present in this file throws. 
+    4) A standard behavior is defined for the most of the properties (get/set appropriate value) when there is number of 
+       overloaded properties, which support more complex behavior using specially written attribute-classes. 
+    5) Changes to the properties are recorded and list of changed properties is available on request
