Huge refactoring to make const what is const (ticket #38), continued.
- too many changes because of too many cross-references to be able to list them up here.
- NOTE that "make check" runs fine and did catch several error.
- note that we had to use const_iterator several times when the map, ... was declared const.
- at times we changed an allocated LinkedCell LCList(...) into
const LinkedCell *LCList;
LCList = new LinkedCell(...);
- also mutable (see ticket #5) was used, e.g. for molecule::InternalPointer (PointCloud changes are allowed, because they are just accounting).
