## Description

simulate() Start the simulation of the previously built system for the specified timeframe.

## Detailed Description and Examples

When simulate is called all subsystems operators are expanded unto the full hilbert space and the complete Hamiltonian is built. The main loop is entered where the full density matrix is calculated for every timestep using an adaptive mix of the time evolution operator and the runge-kutta-4 integration scheme.
