Add collisions

• When 2 particles come close enough to each other, they become one particle.
• New particle's mass will be equivalent to the sum of the original particle's masses
• New particle's momentum will be equivalent to the sum of the original particle's momentums Add visual representation of size
• Radius of particle is proportional to its mass Add initial disk rotation
• When the disk of particles is generated, particles are more likely to have an initial velocity tangent to the center Get simulation settings from user, rather than having them pre-defined in the source code
• Use the console to ask for settings
