Updates towards the end

* CompassBiped
Improved the ZMP calculation to account for the effect of sloped
terrain.
Renamed damnNS and dampS to dampA and dampH since they are applied to
the ankle and hip joints.
Added an option to extend the leg when theta2_dot == 0.

* Analyze
Added the required code for running analysis in open loop ('OL') or
closed loop ('CL').
Added some extra parameters to be calculated: average speed, step
length, gait period, energies, etc.
Removed the ZMP limit when performing the final analysis.

* DisplayGen
Added buttons for showing additional info: walking speed, ground
interaction and energies.
Foot design now uses the extended ZMP calculation.

* MOOGA
Added an option to Find genomes with a fitness value below a threshold
(use '-value').
Also, it is possible to get more than 10 results by using out =
GA.Find(...).

* MOOGA/Plot
Added some formatting to PlotFit

* CheckConvergence
For some reason genomes were converging to period 3... so I started a
prohibition.

* ParetoPlot
Added some formatting.

* Plots4Paper
Small corrections to formatting.
Added a MOOGA statistics plot that displays the genetics of the evolved
genomes separated into 4 clusters.
Genome animations!

Added some functions to animate genomes walking on certain terrains.

* Simulation/Init
Fixed an issue with initializing the rendering

* Simulation/Render
Corrected the way of checking if the figure exists.

* Terrain
Solved a problem with sinusoidal terrain where not enough points were
returned for drawing.
