'''
Pole figure of a gold sample containing 6 grains with a strong <111> fiber texture.
A Microstructure object is first created with the 6 grains of interest.
The grain ids corerespond to the actual grain number (in an EBSD scan for instance).
A PoleFigure object is then created using this microstructure and the pole figures
(both direct and inverse) are drawn by calling the plot_pole_figures() method.
