Static constexpr member function which returns true, if the axis has a bin for every possible input value, and false otherwise. Faster code can be generated if all axes types in a histogram are inclusive. An axis with underflow and overflow bins is always inclusive. An axis may be inclusive even if underflow or overflow bins are missing. For example, a category axis is inclusive if either it has an overflow bin or if it is growing.

Likewise, but non-const member function which returns a reference to the metadata. If this member function exists, also the previous one must exist. Const and non-const member functions must exist, which both returns a mutable reference to the metadata associated with the axis (usually a string).
