SensitivityValdes 2013

Updated the parameter estimation settings to reduce noise in the data.  This
means updating the epsfcn parameter from 0.01 to 1e-8. This parameter controls
the size of the step size used by the parameter estimation algorithm when
estimating the sensitivity coefficients (finite difference).
