Complete the "about" dialog.

For the segmentation process and the simulation, it'd be nice to have a progress bar while the proccesses execute.

The legend should be shown only once the user segments the samples, and not before.

How to use Sphinx library to generate documentation

I suggest the name "Asphalt Mixtures Aging Simulator" instead of "Proyecto-de-Grado-Codes"

In order to speed up the simulation, it is desirable to use cython to calculate Laplacian

Add a widget (or GUI element) in the simulation menu that allows the user to select the slice to be simulated.

The colormaps presents four color in the visualization , instead of the three corresponding to arvoids, aggregates, and mastic.

It is necessary to define a licence of software having clear the differences between GPL, MIT, BSD, LGPL, etc., keeping in mind the restrictions of the libraries used in the project

Please, translate all the comments and documentation to English.

I uploaded a first attempt to the final simulation scheme. There is a issue in the mechanical model output due to the fact that now the output must be the strain on each element and not the displacements.

It is necessary to add a legend in the 3d and 2d views of the sample, so the user can interpret easily the views.

It is necessary to have a description of the project in the front page of the repository
