function hnew = outlinebounds(hl, hp)
%OUTLINEBOUNDS Outline the patch of a boundedline
%
% hnew = outlinebounds(hl, hp)
%
% This function adds an outline to the patch objects created by
% boundedline, matching the color of the central line associated with each
% patch.
%
% Input variables:
%
%   hl:     handles to line objects from boundedline
%
%   hp:     handles to patch objects from boundedline
%
% Output variables:
%
%   hnew:   handle to new line objects
