FUNCTION fCosmoComovDist2ObjectsXYZ

Returns the comoving distance between 2 objects at different redshifts locations in the sphere.

Parameters:

@Redshift1 float: redshift of object 1.
@x1 float: x-coordinate of object 1.
@y1 float: y-coordinate of object 1.
@z1 float: z-coordinate of object 1.
@Redshift2 float: redshift of object 2.
@x2 float: x-coordinate of object 2.
@y2 float: y-coordinate of object 2.
@z2 float: z-coordinate of object 2.
@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 ComovDist float: comoving distance between the two objects.
