tail

auto tail(Range)(Range range,  size_t n) if (isInputRange!Range && !isInfinite!Range &&
    (hasLength!Range ||  isForwardRange!Range))

Return a range advanced to within _n elements of the end of range.

Intended as the range equivalent of the Unix

_tail utility. When the length

of range is less than or equal to _n, range is returned as-is.

Completes in 1 steps for ranges that support slicing and have length. Completes in range.length time for all other ranges.

`range`	range to get _tail of
`n`	maximum number of elements to include in _tail

Returns the _tail of range augmented with length information
