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,:)) %
