1. The changes to the CRATE, FINDAG, HTGF, RGNTHW, REGENT, COMCUP,and SMHTGF
routines eliminate the recursive call from FINDAG to the GETMAX entry
in the HTGF.  The coefficients, or constants, for estimating maximum
tree height were moved from the routines that calculate height
(e.g. the HTGF routine) into the FINDAG routines.  These values are
now passed via subroutine arguments from FINDAG to HTGF.
