int Rohn_Consistency(int dimA,INTERVAL_MATRIX &A)the procedure returning -1 if all the matrices in

To speed up the procedure a remembering mechanism has been
implemented. If the flag
`ALIAS_Rohn_Remembering`
is set to 1
the procedure will store in the array
`ALIAS_Rohn_Matrix`
a set of
at most `ALIAS_Rohn_Remembering_Step` matrices for which the Rohn
test has already been done, together with at which step the test has
failed (the calculation of the determinant of the scalar matrices is
always done in the same order). This may allow to avoid a large number
of determinant calculation.
