emulates the 3D structure of various molecules in Processing

controls: z,x,c to choose which axis to rotate around, then mousewheel to rotate d then mousehwheel to choose nucleus-electron distance a to toggle displaying angles b to toggle displaying unbonded pairs press 'n' then '0-7' to choose number of bonds and then '1-7' to choose number of electron domains to create new atom. ex. 'n 3 5' creates a trigonal planar molecular geometry and a trigonal bipyramidal electronic geometry. 'r' resets rotation
