error in kfold help page regarding future

[yanivabir]

In the kfold.brmsfit help page, the following is given in the example of how to use future:

library(future)
plan(multiprocess)
kfold(fit1, chains = 1)

The call to plan results in an error. I believe it should be:

plan("multicore")

Note both the string and the different term.

In general, the help page is a little lacking as to how the parallelization works. It took me a lot of trial and error to figure out that cores is ignored, and that I should overwrite the threads argument from the original model to match the number of available cores per fold.

I hope the documention is now a bit better.
