Beggining to implement multiscale morris simulated experiments
More on runnable experiments and multiscale morris platform.
Changed maze parameter to Experiment package
Trials are now single run (repetitions are handled as different trials).

Added task to place the robot at the beginning.

Maze parameter are now taken from experiment file and not from
configuration file.
Changed WorldFrame to UniverseFrame
Changed position and rotation handling to use the 3d vectors and 4d
quaternions from Java3D. 
Changed the robot to be directly on the floor and moved the camera up.
Implemented taxic navigator that goes always towards the food.
Format and imports cleaning
Warning purge
Logging framwork for experiments and trials.
Added the concept of subject (rat) to the experiment framwork and specifyer xml file.

Added plotting capabilities to the framework. One plotting script is copied to the experiment loggin folder, which generates plots for all trials and individuals. TODO: execute it automatically at the end of the experiment.

Some file as maze and configuration are copied to the experiment log folder for plotting/traceability purposes.
Renamed random action selection schema and tested that there is no interference between schemas on the same experiment.

Merge branch 'multiscale_experiment' of https://github.com/mllofriu/rat_simulator into multiscale_experiment
logs removal
Added artificial place cell layer to serve as state for the multi-scale q-learning algorithm.

Changed Universe interface to use Point3f instead of Vector3f for positions.
Turned QLearning to single-state version and executed multiple of those.
deleted useless logs
Some ammend on single-state multilayer pcl/qleraning
explorer module
