Description
The setrefdir function sets the reference direction of the
specified components to a new value. The direction is defined by
separately specifying the right ascension and the declination.
The right ascension is specified as a string or a real number (if
raunit argument is not 'time' or 'angle').
The raunit argument is a string that indicates the units for
the ra. It can be any angular unit eg., 'deg', 'rad', 'arcsec',
'mas', or it can be 'time' or 'angle'. If the raunit is 'time'
then the ra argument must be a string in the format 'HH:MM:SS.sss'
eg., '19:34:63.8'. If the raunit is 'angle' then the ra argument
must be a string in the format '+DDD.MM.SS.sss' eg.,
'127.23.12.37'.
Similarly the declination is specified as a string or a real
number and the decunit can be any angular unit or 'angle' or
'time'.

Example
include 'componentlist.g'
cl := emptycomponentlist('crux.cl');
cl.simulate(3);
cl.setrefdir(1, '12:26:35.9', 'time', '-63.5.56', 'angle')
cl.setrefdir(2, '12h26m35.9', 'time', '-63d5m56', 'angle')
cl.setrefdir(3, -173.35, 'deg', '-1.10128', 'rad')
This example sets the reference direction for three newly created
components to the same value.
