TODO: Add description

Buildable is a protocol that allows users to build terms that implement this protocol.

The very basic version of any term type can be implemented with only three functions:

• empty/1: which returns the empty representation of the term;
• insert/3: which inserts an element into the term;
• extract/2: which extracts an element out of the term.

There are other two protocols that get automatically implemeneted, based on the fallback implementations for Buildable, which are:

• Buildable.Collectable: it collects elements into a buildable term. It is analog to Elixir core's Collectable, with a minor improvement.
• Buildable.Reducible: it reduces the buildable into an element. It is analog to Elixir core's Enumerable.reduce/3.

If available in Hex, the package can be installed by adding buildable to your list of dependencies in mix.exs:

def deps do
  [
    {:buildable, "~> 0.1.0"}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/buildable.
