bug fix in check_backup.m and update of help.txt

minor - usefull function that fills donut shaped ROIs

added function to fill nans in matrices

fixed a bug where when the type of some rois was changed, plus some rois added, the type change was not propagated to other timepoints

replaced unused input argumets with '~' (used to be a figure handle that is no longer used within the function)

cleaning.

ADD extended error and pvalue barplot function

Replaced depfun with new matlab function

added listProjectsExpLog.m function that does as the name suggests...

minor - Use NARGINCHK instead of NARGCHK. No funtional change.
