request to add parallel run in structureRun about stratag

[EricArcher]

STRUCTURE doesn't make use of multiple cores internally, so I can't take advantage of that capability in the structureRun() wrapper. The most I could do is convert it to optionally run each value of K on a separate core. Since files are currently being written to the working directory, I need to make sure there won't be conflicts with filenames among the cores (I think the seed file doesn't currently get a special name with the user-specified label at the moment). It'll give me the opportunity to also add the option of writing to (and reading from) a temporary folder as a default which I've wanted to put in place for a while.
Unfortunately, I'm pretty busy with other work at the moment, so I'll have to put this on my future To-Do list.

However, you should be able to create this functionality yourself with something like (untested) :

sr.list <- parallel::mclapply(
  2:5, 
  function(k) structureRun(g, k = k, ...),
  mc.cores = 5
})
