This very simple module sets up fixed redshift n(z) bins for weak lensing.
 We should probably upgrade it to take the redshift from the 
 sampling instead of the ini file.


Assumptions
-----------

 - Delta function window in redshift



Setup Parameters
----------------

   * - dz
     - real
     - 0.01
     - Width of the bins
   * - output_section
     - string
     - wl_number_density
