Diff to previous 5005
scons now runs tests via a testrunner to collect lists of skipped tests in build/ (examples have their own builder since they aren't unit tests)
fixed hessian regularisation tests falling over by adding a shortcircuit optional arg that returns the pde, not the solution
added missing/omitted tests back into scons tests

for a single model inversion, cross gradient case and functional dependence of physical parameters.
