* The code of 'generic_fns/value.py', 'generic_fns/diffusion_tensor.py', and 'specific_fns/model_free.py' has been fixed to properly handle the local tm parameter as well as the global tm parameter.
* The local tm τ<sub>m</sub> parameter can now also be part of the parameter set for an OpenDX map of the chi-squared space.
* The optimisation code has been fixed to handle the unstable, broken Numeric Python packages so that the Cholesky Hessian modification works again and the eigenvalue decomposition (which now freezes Python) is avoided.
