#### Method 1: provide member functions and nested types

This procedure assumes that you have control over the types that should be made conformant to a Range concept. If not, see method 2.

The primary templates in this library are implemented such that standard containers will work automatically and so will boost::array. Below is given an overview of which member functions and member types a class must specify to be useable as a certain Range concept.

Member function | Related concept
--- | ---
`begin()` | Single Pass Range
`end()` | Single Pass Range

Notice that `rbegin()` and `rend()` member functions are not needed even though the container can support bidirectional iteration.

The required member types are:

Member type | Related concept
--- | ---
`iterator` | Single Pass Range
`const_iterator` | Single Pass Range

Again one should notice that member types `reverse_iterator` and `const_reverse_iterator` are not needed.
