Implemented objects for 1D environments (adding them to the environment and including them in the plots).
Added checks for parameters passed during environment initialization that do not apply to 1D environments (holes, walls).
removed the accidental formatting changes! (I definitely agree: no point in making ad hoc changes to the formatting style unless there's an agreed upon plan, so I always aim to match the original style as much as possible)
updated the objects definition to describe objects format in 1D and 2D
Added plot_objects to the doc string for plot_environment().
