.. py:function:: log_integrate_log_trap(log_func, log_support)

   
   Trapezoidal integration of given log(func). Returns log of the integral.


   :Parameters:

       **log_func** : array_like
           Log values of the function to integrate over.

       **log_support** : array_like
           Log prior-volumes for each value.

   :Returns:

       float
           Log of the result of the integral.
