Changes in version 1.5 (2017-06-27)                   

    o   Add new functions for GLMs to extend the same functionality of
	pleio.q.fit, pleio.q.test, and pleio.q.sequential to functions
	of the same name, with the q replaced with glm.  The
	pleio.glm.fit function requires the families of the traits (y)
	and indices of covariates from a user-defined x matrix, and
	vectors of indices of the x matrix that are to be modeld with
	each trait (y).

    o   added vignette for pleio.glm.*, with similar steps as pleio.q.*

    o   If all traits are significant, return pval=1 and indices of all
	traits.

    o   Allow both matrix and data.frame objects for covariates (x.all)

    o   If all genotypes are the same, return empty objects.

    o   Allow either matrix or data.frame for traits (fix for v1.6)

                         Changes in version 1.3                         

    o   Initial CRAN release

    o   Include main functions pleio.q.fit, pleio.q.test and
	pleio.q.sequential, as explained in the vignette pleioQ
