This function computes the accumulated carbon release of the given model as funtion of time.
A Model object (e.g. of class Model or Model14) Have a look at the methods for details.
This function takes a Model object, calculates the release flux as specified by
and integrates numerically the release flux up to each time in
A n x m matrix of cummulative release fluxes with m columns representing the number of pools, and n rows representing the times as specified by the argument
GeneralModel or other model creating functions.
