For now it just makes certain timeAsSeconds is present. Move all such normalization to use this function.

Without it strange things can happen, like autotune trying to change ISF from 56 to 700

Basic usage: just run ~/src/oref0/bin/oref0-simulator.sh. the first time you run it, it will initialize a /tmp/oref0-simulator directory to work in. On subsequent runs it’ll randomly introduce BG noise (defaulting to +/- 10 mg/dL per 5m) and show how the loop responds to that.
If you specify any arguments, it’ll use the first argument as the 5m deviation (a positive or negative integer representing how much you want BG to rise or fall), the second argument as the magnitude of the random noise (a positive integer indicating the maximum absolute value of noise to introduce, which defaults to 10), and the third argument, if provided, as a carb entry. Note that you have to have over 30 simulated CGM readings before it stops reporting Not enough glucose data to calculate carb absorption and starts paying attention to carbs you enter.
oref0-backtest allows you to run the simulator on historical data from Nightscout, or from the deviations from an autotune log file:
