/// Attribute macro for automatic conversion of enums to their string representation
///
/// This macro works only with pure enums (it does not support enums that have
/// values represented as structs)
///
/// This macro implements the following methods:
///
/// ```ignore
/// // returns a Vec of all enum permutations
/// fn list() -> Vec<MyEnum>;
/// // returns the `rustdoc` description of the enum
/// fn descr(&self) -> &'static str;
/// // return the name of the value i.e. `Value`
/// fn as_str(&self) -> &'static str;
/// // return the the namespaced enum value i.e. `MyEnum::Value`
/// fn as_str_ns(&self)->&'static str;
/// // get enum value from the name i.e. `Value`
/// fn from_str(str:&str)->Option<MyEnum>;
/// // get enum value from the namespaced value name i.e. `MyEnum::Value`
/// fn from_str_ns(str:&str)->Option<#enum_name>;
/// ```
