    left,right, colors, startCadTime, endCadTime, modes] = processing(textfile, wkv)

%PROCESSING 
%   The function calls:
%   1. extraction (get text file entries and info)
%   2. matTimeConversion (convert text file entries into wkv timestamps)
%   3. getTimeDoubles (from wkv timestamps get the time doubles
%   corresponding)

%   Through the process, it outputs for further analysis:
%   - for Mode Button: modes [strings], colors, toPlotTimes and endMode_num [wkv timestamps]
%   - for Step Button: left and right [doubles], LeftS_num and RightS_num [wkv timestamps] 
%   - for Cadence Button: starts_num and ends_num [wkv timestamps] 
%   - for All Button & Av Button (Cycles) : ind_PlotTimes, ind_RightS, ind_LeftS (doubles) 
%   (as it is easier to compare indices than timestamps)

%   Hence the function processing.m is called in the following Callbacks: avbutton,
%   allbutton, mode_button, button, cad_button

%% Extraction must be done once to get all data. First run takes time
%operation of the function getTimeDoubles taking time is to process
