Simulator correctness & performance

Every number below is measured, not estimated. Correctness runs five circuits with an exact, hand-derivable closed-form final state (Bell, GHZ-3, GHZ-5, a 4-qubit QFT of |0000⟩, and the Grover preset) through the real simulator and reports the actual deviation from that closed form. Performance times the real simulator on a synthetic circuit at each qubit count, in this browser, on this machine — a run on our server would only describe our server.
