get the parameter matrix right -- not all parameters are going with all initial conditions

• Simulate over broader parameter space by focusing on coarser sequence of environmental variability. E.g., look at varying germination rate and dormant survival for storage effect.
• KEEP unstable to stable sim results for relative nonlinearity. Explain in ms how that may occur (e.g., disturbance).

Need to simulate invasions to estimate stochastic invasion growth rates as a measure of coexistence strength.

I added in the continuous allocation parameter, but coexistence is still really weak unless the growing season (e.g., the number times simulated by the ODE) is really small, like 2. Otherwise the slow growing species always accumulates way more biomass and seed bank because it can grow just a little bit longer than the fast-growing species. So, I think we need to have resource pulses within seasons (events in the ODE) and do the seed germination events between seasons. Seed banks will still only build up during the growing season, so we can still just track end-of-season seed abundance/biomass.

Need to check stability equation b/c NaNs are being produced. Best to break it into pieces instead of one big line.
