Hi Brett   I will collect the codes from this list into this message
It will not include codes that are indented (future plans) / I will go in
order by sections so you can identify and place into /cse along with the
list after the ToC   See you quickly after lunch to get the new figure 
from Cy

    First the list/ no changes from last time

1.1  sparseKTBCcode.m
1.5  harmoniccode.m
1.7  SVDcode.m
2.2  normalmodescode.m
     rosscode.m (was velocityVerlet.m)
     perleapcode ***TO FIND
     see also trapcode.m
