minor changes to optimize the calculation of permuted p-values returned by the functions sig.dim.perm(), sig.dim.perm.scree(), and sig.tot.inertia.perm().
sig.dim.perm.scree() and sig.dim.perm() now return permuted p-values in a dataframe (besides reporting them in the output plots).
minor improvements and typo fixes to the package's help documentation.
first release to CRAN.
