%% Main Script of the framework
% Framework Controls: 
%       a) Compression Methods
%       b) Codec Controllers: for Encoding and Decoding using multiple
%       encoders and decoders
%       c) Decompression Methods
%       d) Evaluation Methods
%       e) Final Results analysis //this is under construction
