allow zero variance? or NA variance #20

MASS::mvrnorm allows 0s. MCMCglmm::rbv does not, but would be easy enough to write in a wrapper function that did it

MASS::mvrnorm implemented (d9adb21), so will work without cov_str. Made wrapper function for MCMCglmm::rbv (rbv0), so need to implement that for pedigree and phylogeny.

made wrapper for mvnfast::rmvn that allows 0s (0cf4fc6)
