Takes the ubiquity system object and other optional inputs to verify the system is running at steady state. This also provides information that can be helpful in debugging systems not running at steady state.

)List with the following names
steady_state Boolean indicating weather the system was at steady state
states_derivative Derivatives that had values greater than the derivative_tol
states_simulation States that had values greater than the offset_tol
som Simulated output
derivatives Derivatives
states_derivative_NA_NaN States that had derivatives that evaluated as either NA or NaN
states_simulation_NA_NaN States with simulation values that had either NA or NaN
derivative_tc Data frame with the timecourse of states where the derivative was found to be greater than tolerance (states_derivative)
ubiquity system object
optional set of parameters (NULL) to check at steady state (if set to NULL then the parameters for the currently selected parameter set will be used)
Boolean value to control removing all rate inputs (TRUE)
Boolean value to control removing all bolus inputs (TRUE)
sequence of output times to simulate for offset determination (seq(0,100,1))
maximum percent offset to be considered zero (.Machine$double.eps*100)
maximum derivative value to be considered zero (.Machine$double.eps*100)
time to evaluate derivatives to identify deviations (0), set to NULL to skip derivative evaluation
