Issue #21 * Updated documentation. Issue #21 * Added `CHANGELOG.md`. * Also convert case when deriving `Display`. Issue #21 * Added `EnumDiscriminants` derive. Issue #33 * Added the ability to rename derived `EnumDiscriminants`. Issue #33 * Updated `README.md` and lib.rs docs. Issue #33 * Updated `CHANGELOG.md`. Issue #33 * WIP: refactoring to allow attributes on discriminants enum. * Use single `strum_discriminants` top level attribute. Issue #33 * Allow multiple declarations of `strum_discriminants` attribute. Issue #33 * Pass through all other attributes to discriminant enum. Issue #33 * Add `impl From<MyEnum> for MyEnumDiscriminants`. Issue #33 * Add `impl<'_enum> From<&'_enum MyEnum> for MyEnumDiscriminants`. Issue #33 * Added complex case test for `From` derivation.
