measuresdata - read IERS and other data for Measure conversion

       The  measuresdata  program is able to analyse ascii tables (or sinex files or xml files) and convert them
       into casa Tables which can be used by e.g. the Measures class.

       The files have to be obtained by other means (e.g. a python script, manually or another script (e.g.  the
       provided measuresdata.csh tcsh script.

   Normaloperation
       1.     Call  the  program  measuresdata.  The  program  can  have  arguments (see later, but the defaults
              suffice. The program will produce a cout log.

       2.     The program will return with either a failure status or with success  status.  In  latter  case  a
              resource file (measuresdata.rc) will be present. This file will have format:

               status: [end|cont]
               ftp: <node-address>
               dir: <ftp-directory>
               file: <ftp-file>
               data: ascii
               arg: <arguments to call back to measuresdata>

              If  the  status  is  given  as  'end' the program is finished; if it is given as 'cont' the script
              should obtain the file given by ftp, dir and file and call measuresdata back with all the info  in
              arg.

       3.     Loop with calls to measuresdata

       The  arguments  to measuresdata are given in casa 'Inputs' format. I.e.  as 'key=value'. In the following
       the key is followed by default.

       type=ALL|IERS|JPL|TAI_UTC|....
              Type(s) of tables to produce. Default: all

       in=<filename>|-
              Input ascii file. Normally determined by measuresdata program. Default: -

       refresh=y|n
              Force a table refresh within the minimum refresh period. Default: n

       renew=y|n
              Force a table renew, rather than an update, if table has to be refreshed.  Default: n

       derange=yyyy,yyyy
              The wanted range for the JPL planetary tables. Default: 1960,now+20

       dir=<filename>
              Base directory for tables. Default: .
