    Wrapper for the IDL function tiny tim as created by
    Richard

    INPUTS : X,Y : A VECTOR CONTAINING THE PIXEL POSITIONS
             OF THE STARS WE WANT

    ARGS : ALL THE ARGS WE WANT TO GO INTO TINYTIM_CREATE
           IF IT IS A STRING IT MUST HAVE QUOTES AROUND IT

    EXAMPLE :
    tinytim.run( x, y, focus_range=focus[iImage], \

                            exact_position=1)
