Detailed Description

template<typename Iterator, typename EndIterator = Iterator>
class emlabcpp::view< Iterator, EndIterator >

Generic class to represent view of some container.

The view stores iterators to the input container and acts as container.

Note: is_view_v<T> can be used to detect if T is view
