Updated g_kapeAnalysis.m

	The way in which subject lists are supplied to g_kapeAnlaysis is
	changed. Before the subject IDs were included in the script; now
	the script has a compulsory input argument for the subject list
	file name. I added an example subject list file called
	"grp_subj_list.m".

	Usage example:
		g_kapeAnalysis('grp_subj_list')
		g_kapeAnalysis('grp_subj_list', 'femaleOnly')

	In addition, please download the following files to the
	commonmcode directory:
		read_struct_from_file.m
		splitstring.m
	These files are required by the new g_kapeAnalysis.m
	Note that the commonmcode is one of my git repositories:
