- quick and dirty addition to the optimizer: now tries repeatedly with looser and looser tolerances.

To fix:
1) hard-codes parameters in
2) replicates much of the roxygen documentation between BayesianLR.test and run.BayesianLR.test
- Repeatedly running while backing off on the parameters is now working, with more sensible defaults.  Added in maxTries as a parameter rather than hard-coding it.
