 cutoffs are determined per atom collections, a collection specifier is needed and
 cutoff for one or multiple collections can be extended. Also ranges of collections
 using the usual asterisk notation can be given. 
+Collections are indexed from 0 to N-1 where N is the total number of collections.
 Note that the arguments for *cutoff/multi* are parsed right before each
 simulation to account for potential changes in the number of collections.
 Custom cutoffs are preserved between runs but if collections are redefined,
