shapeless-2.2.3 released

[Miles Sabin]

This is the final release of shapeless-2.2.3.

These release notes provide a summary of changes since shapeless 2.2.2.
shapeless 2.2.3 is source and binary compatible with shapeless 2.2.0+
and should be binary compatible with shapeless-2.1.0 in most cases.

The changes are,

• Generic1 now supports nested type constructors.

• Added an Adjoin type class which flattens HLists and
  Coproducts by one layer (thanks to Travis Brown).

• Fixed an incompatibility between cachedImplicit and the orphan type
  class derivation mechanism (#391).

Contributors for shapeless 2.2.3 are,

• Travis Brown (@travisbrown)

Many thanks to all of you and everyone else who has contributed ideas,
enthusiasm and encouragement.
