Header-only C++17 library provides static reflection for enums, work with any enum type without any macro or boilerplate code.
* `enum_cast` obtains enum value from string or integer.
* `enum_integer_value` obtains integer value from enum value.
* `enum_value` returns enum value at specified index.
* `enum_values` obtains enum value sequence.
* `enum_count` returns number of enum values.
* `enum_integer` obtains integer value from enum value.
* `enum_name` returns string name from enum value.
* `enum_names` obtains string enum name sequence.
* `enum_entries` obtains pair (value enum, string enum name) sequence.
