Added the sparse noise
Second change to visual
Modification Monday 03
I wrote the experiment classes and the topographica classes for the sparse and dense noise. They are documented and have time controls however they are not yet debuged.
Modification of the lasts days that plot and animate the simulation properly. Also, the functions for the sparse and dense noise with variable pattern_size have been added successfully
Experiments properly set
Animation running with the proper bounds for the text
Topographica based correctly called

Still documentation is not perfect
Up to date vision and topographica experiments, properly documented
