**  Given:
**     epb      double    Besselian Epoch (e.g. 1957.3)
**
**  Returned:
**     djm0     double    MJD zero-point: always 2400000.5
**     djm      double    Modified Julian Date
**
**  Note:
**
**     The Julian Date is returned in two pieces, in the usual ERFA
**     manner, which is designed to preserve time resolution.  The
**     Julian Date is available as a single number by adding djm0 and
**     djm.

**  Although the intent is to replicate the SOFA API (other than
**  replacement of prefix names) and results (with the exception of
**  bugs;  any that are discovered will be fixed), SOFA is not
