- Development of a function to calculate the number of metric neighbors.
- changed the value of the distance that a agent can move and will not be considered as a change in his position.(10% -> 1%)
Added the number of converged samples to the metric neighbors calculation.
Added a function to calculate the mean distance between the agents

Removed from class Swarm functions that has no relation with dynamics.
Removed all warnings from the codes, but the main.cpp still have warnings,
there is a need to make a better shell menu.
reated a new file to hold analysis functions (analytics.h)

Removed stuff from swarm.h to analytics.h.
changed the shell menu at the main.h

Generalized a function that will receive another function that receives a swarm and return a double,
the former function will print the mean, std and number of converged agents.
Created new functors to calculate the mean, std and the covergence of the ensemble.
New menu to print all quantities and area calculation

Updated the shell menu, added a option to print all quantities and to plot.
Created a function to calculate the area that the swarm occupies.
Added a new parameter to swarm class to set the side of the  initial condition square.
Added a function to return the mean angles modulo 60.

Also added this quntitie to --all on the shell menu.
And added a test for it.
Added a funtion and a bug correction

Created a function to claculate the number of agents inside a circle.
Corrected a bug on metric neighbors functio, was missing a fabs.
Bug correction on the angles list function

The function was returnig nan because the acos function,
using the acosf  function solves the problem.
Shell menu modification to printe the quantities in different files
Added psi6 quantitie
Repaired Psi6 quantitie, and added test to it
Removed menu functions from main.cpp and moved to menu.hcommitted)
Created a option on the menu to print the final psi6
This function must be generalized to print all quantities.
Created tests and angles measures

Created a function to count the number of angles that are multiple of 60 degrees.
Created a script to loop throug different angles.
Ajusted the tests for all quantities.
Tests of the last commit
first commit with submodule rack
Add PPGnuPlot

Removed the the old C lib to use Gnuplot and added PPGnuPlot.
To do that, I had to change some things on the Swarm and Agent class,
so they operator[]s, was in conformance whith PPGnuplot interface.
Refactor and of agent class

Moved functions from .h and .cpp to geometry files.
Added method operator++ and size.
refactored the distance, that is the distance beteween agents.
