function plotViolin(features,options)
%   
%   plotViolin(features,options) plots the distribution of a matrix of
%   features. Each column of the matrix is a feature.
%
%   Input parameters:
%       - features: matrix of features. Each column is a feature, whereas
%                   each row is an instance (subject).
%       - options:  struct that contains the customized params.
%             * options.Xlabels:      Labels of the x axis (groups)
%             * options.Ylabel:       Label of the y axiz (feature)         
%             * options.Colors:       Colors of the boxplots (one per group/column)         
%             * options.PlotSize:     Size of the figure

%   Example of use:
%
%   features=rand(100,2);
%   options.Xlabels={'group #1','group #2'};
%   options.Ylabel={'myFeature'};
%   options.Colors=[0.3 0.5 0.5;0.8 0.1 0.1];
%   options.PlotSize=[400 500];
