Enables merging several groups into a single one.
joinGroups()
None.
This function is the most useful to merge several groups, defined e.g. on the 
basis of a classification plot. A simple spreadsheet is invoked with two columns, 
the first ('Old') containing the old levels of groups and the second, 
'New', which can be edited. Finally, groups with identical names will be 
merged into a single one. 
Optionally, the vector containing the information on the current groups can be 
appended to the data frame 'labels'.
