[ADMB Users] MAR(1) -needing Var operator and Kronecker product

[dave fournier]

To write efficient df1b2variable code for moderate to large size 
matrices M with

     y=solve(M,x)

one needs to write the df1b2variable equivalent of adjoint code for the 
LU decomposiiton.  This is not too difficult but not the most 
interesting exercise in the world.
