Added two config files for the 2 step dic and learn scripts; removed 'extra' folder; created init script (initial version).

function DL = SMALL_learn(Problem,DL)
%% SMALL Dictionary Learning   
%   
%   Function gets as input Problem and Dictionary Learning (DL) structures 
%   In Problem structure field b with the training set needs to be defined
%   In DL fields with name of the toolbox and solver, and parameters file 
%   for particular dictionary learning technique needs to be present.
%
%   Outputs are Learned dictionary and time spent as a part of DL structure
