Inputs

seq	a sequence
n	a non-negative integer

Outputs

before-slice	a slice
after-slice	a slice

Word description
Outputs a pair of sequences, where before-slice is a slice of the first n elements of seq, while after-slice is a slice of the remaining elements.

Notes
Unlike cut, this is suitable for use in an iterative algorithm which cuts successive pieces off a sequence.
