%REMOVE_USERFCN Removes a userfcn from the list to be called for a case.
%   MPC = REMOVE_USERFCN(MPC, STAGE, FCN)
%
%   A userfcn is a callback function that can be called automatically by
%   MATPOWER at one of various stages in a simulation. This function removes
%   the last instance of the userfcn for the given STAGE with the function
%   handle specified by FCN.
