+ #10/13/2005: exntended to remove variables of the form %tmp(.#)* rather than just 
+ #%tmp.#, i.e. it now will remove %tmp.12.3.15 etc, additionally fixed a spelling error in
+ #the comments
+ #10/12/2005: now it only removes nodes and edges for which the label is %tmp.# rather
+ #than removing all lines for which the lable CONTAINS %tmp.#
