Implement Erlang Standard Library calls in Elixir Standard Library

issue から未チェックの関数を1つ選び、まずリンク先の Erlang ドキュメントを読んでください。src/javascript/lib/core/erlang_compat に実装し、その関数のテストを追加して、pull request を開く前に動作が Erlang ドキュメントと一致することを確認してください。

Below is a list of all the known Erlang standard library functions found in Elixir's Standard Library that have not been implemented in some way yet in ElixirScript. Implementations should go here

For anyone looking to implement a function the steps would be to:

• Pick a function or functions from the list below
• Implement the function(s) in JavaScript according to the Erlang docs
• Add tests for the function(s) implemented
• Make Pull Request

Then we can check off those functions is the list below
