This is an R package to refactor the association testing code in GENESIS into something easier to maintain and optimize. It is currently named "genesis2_tests" for lack of better ideas, but we will rename it in future.

This package will contain the null model code and basic association testing functions, and will take only simple objects (data.frames for phenotypes, matrices for covariance and genotypes). A separate package will deal with preparing data (reading from GDS, etc) to pass to the functions in this package.
