-- 1.0-beta5: Fixed bug about initialization of variables in ParticleStorage. Storage classes defined in separate header/source for clarity. Two example files. One shows basic usage and one more advanced usage.
-- 1.0-beta4: Mass infomation is now calculated/cached only if requested and not by default. This further reduces computation time.
-- 1.0-beta3: Some classes renamed for clarity. Critical information about single particles is now cached to reduce computation time.
