There are two new hk programs to manage the hk data in 30-day series. 

hk30make will make and ingest 30-day datasets of all the hk data 
for the given series numbers. Here are typical ds:

  prog:mdi,level:cdrom,series:mdi_hk12_30d[35]
  prog:mdi,level:cdrom,series:svm_hk1_30d[35]
  prog:mdi,level:cdrom,series:svm_hk2_30d[35]
  prog:mdi,level:cdrom,series:svm_hk3_30d[35]
  prog:mdi,level:cdrom,series:svm_hk4_30d[35]

After the ds are made the corresponding files are removed from the
/PAS1/hk dirs. The links in /mdi/mdi_egse_data/log/mdihk and
/mdi/mdi_egse_data/log/schk are now "stranded".

hk30restore will restore the hk 30-day datasets given. The ds are
retrieved into /PDS storage and the links in
/mdi/mdi_egse_data/log/mdihk and /mdi/mdi_egse_data/log/schk 
are made to the corresponding files. These links are now "live"
again until the ds is removed by the normal ds removal process.

Here are the auto-descriptions:

> hk30make
Make 30-day datasets of hk data for the given range.
Remove the hk files that are made into datasets.
Usage: hk30make start_30day_series# [end_30day_series#]
(NOTE: 30day series# can be gotten from time_index)

> hk30restore
Restore 30-day datasets of hk data for the given range.
Brings the ds online and links the master mdi hk dirs 
/mdi/mdi_egse_data/log/mdihk [schk] to the corresponding files.
Usage: hk30restore [-t#] start_30day_series# [end_30day_series#]
where -t# = touch, number of days before mark ds del pend (default 2)
(NOTE: 30day series# can be gotten from time_index)


We have agreed that in practice we will keep only the last year of
hk data online in the /PAS/hk area.
