FUNCTION fCosmoZfromDa

Returns a row with the first and second solution for the redshift, given an angular diameter distance.

Parameters:

@AngularDiamDist float: angular diameter distance in Mpc.
@OmegaM float: matter density. If set as DEFAULT, then 0.27891507
@OmegaL float: dark energy density. If set as DEFAULT, then 0.721
@OmegaR float: radiation density. If set as DEFAULT, then 8.493e-5
@omega0 float: dark energy state equation. If set as DEFAULT, then -1
@h_0 float: (hubble constant[Km/s/MPc])/(100[Km/s/MPc]). If set as DEFAULT, then 0.701 Reference: http://lambda.gsfc.nasa.gov/product/map/dr3/pub_papers/fiveyear/cosmology/wmap_5yr_cosmo.pdf

returns table (z1 float, z2 float): one row table where z1 and z2 are the first and second solutions, and z1<=z2.
