do.rep: Evaluate a function repeatedly over arbitrary arguments
In patr1ckm/distributr: Grid Search with SGE Backend

This idiom is really useful to carry out simulations, which are essentially repeated evaluations of a function over a grid of parameter values.

1 2	do.rep(.f, ..., .reps, .verbose = 1, .rep.cores = 1, .eval = T, .args = NULL)

`.f`	function to be evaluated
`...`	Arguments passed to f
`.reps`	the number of times the function should be evaluated
`.verbose`	If `1` (default), prints a `.` with every completed condition.
`.rep.cores`	Apply repeates in parallel using mclapply
`.eval`	If `TRUE` (default), evaluates `f`. If `FALSE`, does not evaluate `f`.
`.args`	optional list of (named) arguments to .f If `2`, prints the arguments corresponding to the completed condition. If `3`, prints the arguments and results of the completed condition.
