cake all generates all programs

Smoothwell.x smoothes log using triconv

gardner.x generates density from Gardner's relation

welltogroup.x converts from convetional well logs to S+M group domain

grouptogenlog.x converts from S+M group domain to elastic stiffness log

randvel.x generates a random p and s velocity log


*******************************************************************************
smoothrand.sh	generates a random p,s,rho log and smoothes it directly and 
		using S+M (it's the most general shell)
******************************************************************************

smooth.sh	like above , only 3 layers


test shells for various simple cases:
test1.sh
test2.sh
test3.sh
test4.sh
test5.sh
