Rendering methods

renderingSpin - A module able to represent atoms by their position and spin.
renderingAtomic - A rendering method to draw atoms positioned in a box.
renderingAtomic_d3 - Method to load d3 position file.
renderingAtomic_ascii - Method to load ascii position file.
atomic_xyz - Method to load ascii position file.

Main purpose of V_Sim is to render some file describing positions and other informations n a graphical way. This is achieved implementing #RenderingMethods. Currently two methods exist, one draw spheres (or other geometric forms such as cubes) on defined positions. The other is a more specialised version of the former, adding a direction information on each position. Ths method is called SpiRendering and is usefull to render spin configurations.
