## Revision 1.7 1998/07/30 11:29:54 peterg
## Added implicit integration stuff
##
## Revision 1.6 1998/07/30 10:44:37 peterg
## INcluded othe integration methods.
##
## Revision 1.5 1998/07/26 11:02:20 peterg
## Put mtt or MTT in front of variable names to avoid clashes with
## globals
##
## Revision 1.4 1998/07/25 20:14:00 peterg
## update code added for flexibility and octave efficiency
