   Variables that can be set in mat3d.mesh :
   colors = Colors   - Sets the colormap
   linewidth = 0.1   - Sets the width of the plotlines
   precision=3       - Sets the number of digits accuracy for the text on the axis    
   num_ticks=5       - Number of ticks on axes, evenly spaced 
   fill_mesh = 0     - If one, fills the mesh with the colormap in colors"""
