Changed mxTryHard()'s "objective function" references to "fit function", since that's what they're called in 2.0; add condition to use best fit if most recent fit ended in error.
Modify .svnignore files. WLS branch and trunk changes. Added continuous only wls test. Found and added state space algebra test.
Move more CI code from frontend to backend This avoids the need to find the size of an mxAlgebra in the front end.
