Many new features added: 1. getting S2 values 2. possibility of setting position of hole 3. possibility of setting Sbox 4. three Sbox definitions at once 5. Doing only FAM1 or the full set of states 6. efficiency improvements

subroutine searchdet(deti,add,dethi,addh)

BEGIN_DOC
|
|
! this subroutine is at the heart of the idea
|
|
! it will generate all the determinants in a fixed order
|
|
! then find the posistion of the determinant given and
|
|
! return it's position in add.
