Enable sending all output to one directory

See https://github.com/oguzhanogreden/SimDesign/issues/3.

Experiencing that this is needed for a smooth experience while using one of the widely available computing infrastructure solutions in the Netherlands, I thought I'd suggest this here.

In case this will go through, following are needed:

1. SimClean() needs to be adjusted.
2. MPI may need adjustment, see analysis.R line 31.

Can you provide a simple example demonstrating this change? The concept itself seems fine to me, I'd just like to test it out before merging and documenting.

Here it is.

You'll notice there's no check for whether the specified folder exists. Since there are safety checks in place, I considered it not relevant. a suppressWarnings() could be nice at line 750 here, otherwise there's a warning which may create a glitchy feeling.

Design <- expand.grid(mean_diff = seq(0, 1, by = .1), 
                      sample_size = c(10, 20, 30))

#--------------------------------------------------------------------

Generate <- function(condition, fixed_objects = NULL) {
    ret <- with(condition, rnorm(sample_size, mean_diff))
    ret
}

Analyse <- function(condition, dat, fixed_objects = NULL) {
    ret <- c(p = t.test(dat)$p.value)
    ret
}

Summarise <- function(condition, results, fixed_objects = NULL) {
    ret <- EDR(results, alpha = .05)
    ret
}

#--------------------------------------------------------------------

### Run the simulation (using all available cores)
results <- runSimulation(Design, replications=50, verbose=FALSE, parallel=TRUE,
                         generate=Generate, analyse=Analyse, summarise=Summarise, edit='none',
                         save = T, save_results = T, save_generate_data = T,
                         save_details = list(out_rootdir = '~/far_away'))

Thanks. This seems reasonable to me. Also note that dir.create() has a showWarnings flag to remove the warning you described. I'll merge this and add these components in when I document the change.
