ensemble_filt_practicedata

 Removes practice trial data from stim_meta, response_data, and stim_Xattribute 
 structs produced by ensemble_load_expinfo.m. Output is expinfo struct
 with practice-related data filtered out. This is useful when some of the 
 trials presented in an Ensemble-controlled experiment are practice trials
 and one does not wish to include those trials in subsequent analyses.

 INPUT
   expinfo (as produced by ensemble_load_expinfo.m)
   params.practice_attrib -- attribute name associated with practice trials in Ensemble
