Bulk rekey your maps. Simple bud. (☞ﾟ ヮ ﾟ)☞

### Why?

Simply because I am _super lazy_, and writing out functions to take maps and convert them to different keys was boring (and irritating) me.

Stop writing `defp from_x_to_y(data), do: %{ "another_id" => data["id"], "name" => data["title"] }`.

### TL;DR; Syntax

1.  Macro: `content<~>transformation`, content is your data, transformation is your rules.

2.  Content: Any map. BYOD.

3.  Transformation: `from=>to`. Left is the original key, right is the new key.

## Getting started

```elixir

def deps do

  [

    {:map_rewire, "~> 0.3.0"}

  ]

end

```
