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}. UGH!

o Moved grid from Depends: to Imports:
o Now use markdown in package documentation for easier maintenance, via {roxygen2md}
