function ori0 = loadOrientations(input,cs,ss)
% Function to load grain orientations from a file
% 
% Input file should be a simple list of Euler angles, one orientation per line
%   first column: phi1
%   second column: Phi 
%   third colum: phi2
%
% Parameters:
% - full path to the file with the list of euler angles
% - cs: crystal system
% - ss: sample system
% 
% Returns
% - A list of orientations
