| static HRESULT | step (const FloatP_t &until=0, const FloatP_t &dt=0) |
| | Performs a single time step dt of the universe if no arguments are given. Optionally runs until until, and can use a different timestep of dt.
|

The universe is a top level singleton object, and is automatically initialized when the simulator loads. The universe is a representation of the physical universe that we are simulating, and is the repository for all physical object representations.
All properties and methods on the universe are static, and you never actually instantiate a universe.
Universe has a variety of properties such as boundary conditions, and stores all the physical objects such as particles, bonds, potentials, etc.

Get the universe temperature.
The universe can be run with, or without a thermostat. With a thermostat, getting / setting the temperature changes the temperature that the thermostat will try to keep the universe at. When the universe is run without a thermostat, reading the temperature returns the computed universe temp, but attempting to set the temperature yields an error.
