parallelise the main permutation test (not pairwise ones yet)
update with new argument parallel and description
parallelise the pairwise tests too
correct the calls; remove argument control which doesn't exist
simplified default for argument permutations
Merge branch 'parallel-betadisper'
remove note about non-parallel pairwise tests
document the parallelism for betadisper permutations
really remove the note that I claimed to have removed in 14234d12e8e05accfefa7ff94314af58afb1a6c8
remove note about parallel only being in R 2.14.x or later as vegan depends on a later version of R than this
use 99 permutations in examples
