- Minor cleanup on package structure so it returns fewer warnings when CHECKing (still 3 to eliminate)
- BayesianLR.test is now working for maxed out (testPos==truePos) sensitivities, as well as for non-maxed out sensitivities and specificities.

- Remaining to do:
    - Write print and summary methods for class lrtest
    - Work out maxed out specificities
