setupmobile
function setupmobile
%   SETUPMOBILE Adds directory where sensorgroup functionality resides to MATLAB path.
%
%   SETUPMOBILE Adds directory where sensorgroup functionality resides to
%   MATLAB path. It uses addpath and savepath functions which modify pathdef.m
%
%   If direcory where sensorgroup functionality resides is deleted 
%   in order to prevent warning during MATLAB startup MATLAB path has to be 
%   cleared by running savepath command.
