33 // Class description:
34 //
35 // A FastAerosolSolid is a collection of fDroplet solids
36 // with positions set randomly by FastAerosol in a
37 // volume given by a bulk shape given by FastAerosol member
38 //
39 // The FastAerosol member fCloud handles the optimization
40 // (finding nearest droplet, populating the cloud) needed for
41 // efficient simulations.
42 //
43 // This class is heavily based on system solids.
