Convert input pixel position(s) into RA/Dec position(s).
Output will be either an (ra,dec) pair or a 'list' of (ra,dec)
pairs, not a numarray, to correspond with the input position(s).

Parameter:
    input - Filename with extension specification of image
    pos   - Either a single [x,y] pair or a list of [x,y] pairs.
    idckey - Keyword which points to the IDC table to be used.
