gmRemove deletes the specified object in a geometallurgical database. This may include the removal of all its members, too.
If you only want to remove a certain attribute for an object, than use the argument var for specifying. In the case of this attribute being an object itself but not a value, you may have more than one entry to choose for deleting. Therefor choose the right one by stating an id or an gmExpr in the which argument.
