/**
****************************************************************************************************
* @run MojObject stores key-value pairs.Internally it provides separate implmentation
for all data types. Provides facility to push single entry or entire array
of data into MojObject.
Supports put/get/delete operation.
Data having key and value is converted to Node type and then node is inserted
into TreeBase. All operation happens on TreeBase are based on key.
Provides interface to convert JSON string to JSON object and viceversa.
