Function set_taxis

  Make RKS or TPS block by specifying begintime, endtime,
  timeunit and timestep.
  
  

CALL:

   S = set_taxis(S, tbegin, teind, tijdstapeenheid, tijdstap)
  
  

INPUT:

   S:               Existing RKS or TPS administrationbuffer, may be empty.
   tbegin:          Datenum with begin time.
   teind:           Datenum with end time.
   tijdstapeenheid: (Optional) String with timeunit, 
                    see DONAR Manual Part 7, section 2.9.3
   tijdstap:        (Optional) timestep in tijdstapeenheid units.
  
  

OUTPUT:

   S: Structure with RKS or TPS (reeksadministratiebuffer) with new values.
  
  

APPROACH:

   Convert Matlab datenum to DONAR date and time.
   Substitute values. Check if timeunit en timestep need to be added.
   Check if timeunit and timestep are valid
  
  

EXAMPLE:

   blok = emptyblok;
   blok.RKS=set_taxis(blok.RKS,now-1, now+1);
