[section:copy copy]
[heading Prototype]
``
template<class SinglePassRange, class OutputIterator>
OutputIterator copy(const SinglePassRange& source_rng, OutputIterator out_it);
``
[heading Description]
`copy` copies all elements from `source_rng` to the range `[out_it, out_it + distance(source_rng))`.
The return value is `out_it + distance(source_rng)`
[heading Definition]
Defined in the header file `boost/range/algorithm/copy.hpp`
[heading Requirements]
* `SinglePassRange` is a model of the __single_pass_range__ Concept.
* `OutputIterator` is a model of the `OutputIteratorConcept`.
* The `value_type` of __single_pass_range__ Concept is convertible to a type in `OutputIterator`'s set of value types.
[heading Precondition:]
* `out_it` is not an iterator within the `source_rng`.
* `[out_it, out_it + distance(source_rng))` is a valid range.
[heading Complexity]
Linear. Exactly `distance(source_rng)` assignments are performed.
