This is a Baseclass to handle common functionality to both the response and query handler

this contains a reference to messagehandler which the derived class can make use of using 

the MessageHandler() api

A reference to cache entry to be passed in order to build a cache wrapper as cache requires

all the records to be present in the CacheEntry variable.

Seperate functions are provide to handle address,pointer,text and srv records as , same can 

be used by both query and response handler.
