% JT_SLAM_FILTER - Generates a new SLAM filter structure whose
%                  belief state is a junction tree.  This is
%                  equivalent to using the information filter.
%
% Usage:
%
%   f = jt_slam_filter(m, C, width, overlap[, sig])
%
% Inputs: 
%
%   m       - the starting state of the robot
%   C       - a positive definite matrix giving the covariance
%             (uncertainty) in the robot's initial state
%   width   - the maximum cluster size of the junction tree 
%   overlap - the maximum separator size of the junction tree
%   sig     - if non-empty, this is the significance threshold
%             used in adaptive message passing (default: [])
