5.97
1.  Changed dfloat  to dble  per BDR's email of 19/08/23

5.98

1.  On the advice of BDR the arithmetic ifs in cholsky.f were modified to
accord with "modernization" of fortran.  And the Do loops in crqf.f \ 
were also
modified to end with CONTINUE.

2.  Some syntax issues identified in the new CRAN checks were also made.

5.99

1.  Bug in rq.fit.conquer fixed to allow ci to be passed to conquer::conquer.

2.  cp cholesky.f from SparseM to remove computed gotos in the quantreg
version

3.  changed several calls to model.matrix to use contrasts.arg = rather than
contrasts =
