An algorithm to generate clumped-sphere approximations of non-spherical particles

An algorithm to generate clumped-sphere approximation of non-spherical particles from particle STL files (X-ray micortomography, Selective Electron Microscopy etc), to be use in Discrete Element Simulations.

Features:
1. Can write the clumped-sphere assembly in TECPLOT format for visualisation.
2. Outputs the moment of inertia, volume of the assembly and the errors by comparing to direct MC calculations (this is time consuming).
3. Writes Lammps templates of the assembly.
4. Possibility to control surface features, (if using large smoothing a rescaling of the sphere diameters may be required, see the paper for a discussion.
