Formula Interface for Split

Implementation of a simple formula interface for the split function.

## S3 method for class 'formula'
 split(x, f, drop = FALSE, data = NULL, ...)

`x`	a formula of the form `y ~ x`.
`f`	a 'factor' in the sense that `as.factor(f)` defines the grouping, or a list of such factors in which case their interaction is used for the grouping.
`drop`	logical indicating if levels that do not occur should be dropped (if `f` is a `factor` or a list). Defaults to FALSE.
`data`	the data frame from which the formula should be evaluated.
`...`	other arguments to be passed to `split`.
