%INITMAP Initialize map for experiment.
%   M = INITMAP(MODE,NAME,PARAMS) initializes the map M for a slam or
%   localization experiment. With MODE = 0 the map is prepared for a
%   slam experiment: a map M with name NAME is created, a robot is
%   created, added to M and set to its initial pose PARAMS.XRINIT,
%   PARAMS.CRINIT. With MODE = 1, the map is prepared for a locali-
%   zation experiment: a map file with name NAME is opened, read in
%   and the robot is set to the initial pose as above.
%
%   The PARAMS structure is defined in the setup file of the experi-
%   ment.
