function [ X,header ] = pnBaseFeatures(data)
%PNBASEFEATURES Extract base features for a given model
% [ X,header ] = pnBaseFeatures(data,featType) extracts features for the data
% using the 'Base' method ONLY.
%
% Inputs:
% data - Cell array of data.
% Column 1 - Subject IDs
% Column 2 - Time stamp vectors for each subject
% Column 3 - Feature name vectors for each subject
% Column 4 - Data value vectors for each subject
%
% Outputs:
% X - Double matrix NxD with D features needed for training.
% header - Cell array 1xD of labels for each feature used.
%
%
% Example
% bpath = './set-a/';
% data = pnLoadTextFilesCell(bpath);
% stat = pnBaseFeatures(data(1,:)) %
