Put plotting tools in visualization, rather than examples

[joseortiz3]

Hi there, your package works well in Python 3.7.1 on Windows.

For plotting, instead of giving examples in the documentation page, perhaps put plotting tools inside the visualization module / library.

For instance,

def plot_copula_3d(copula,plot_type='pdf',subplot=None):
    """Plots a pycopula copula object's pdf or cdf.

        Usage: 
            plt.figure()
            plot_copula_3d(copula,'pdf')
            plt.figure()
            plt.subplot(2,1,1)
            plot_copula_3d(copula, 'pdf', (2,1,1))
            plt.subplot(2,1,2)
            plot_copula_3d(copula, 'cdf', (2,1,2))
            plt.show()
    """
    if subplot is None: ax = plt.gca(projection='3d')
    else: # Overwrites the entire figure with single plot
        fig = plt.gcf()
        ax = fig.add_subplot(*subplot,projection='3d')
    if plot_type=='pdf':
        u,v,C = pycopula.visualization.pdf_2d(copula)
    elif plot_type=='cdf':
        u,v,C = pycopula.visualization.cdf_2d(copula)
    X, Y = np.meshgrid(u,v)
    ax.plot_surface(X,Y,C)
    ax.plot_wireframe(X,Y,C,color='black',alpha=0.3)

Hello,

Thank you for your feedback. This package is still under development, and documentation is not very helpful at the moment. In the future, I will mainly focus on how to easily plot copulas, concentration functions of scatter plot to help users.
