This is a major release of the package, fixing bugs and revising documentation

o Added tests for CMHtest() PR #13 [Thx: Daniel Sabanes Bove] o Automatically omit strata with a single observation in CMHtest() because they do not contribute to the test statistics o Use the generalized Moore-Penrose inverse from MASS in CMHtest() such that it can work when the variance matrix is singular. o Converted the package to use roxygen documentation via {rd2roxygen}.
