enhancement - started implenting handling for spike data, see http://bugzilla.fcdonders.nl/show_bug.cgi?id=1514. Since spike data has {chan} as pissible dimension, this needs to be treated more like {pos} and {rpt}. Changed the time/trial selection for raw data, there might be a potentiall issue still with this.
