Enhance Ecto with powerful queries.

## Installation

The package can be installed by adding `queryable` to your list of dependencies in `mix.exs`:

```elixir

def deps do

  [

    {:queryable, "~> 0.1.0"}

  ]

end

```

## Documentation

Documentation can be found at [https://hexdocs.pm/queryable](https://hexdocs.pm/queryable).

## Usage

Extend an Ecto Schema by adding criteria:

``` elixir

defmodule Person do

  use Queryable #instead of Ecto.Schema

  schema "persons" do

    field :name, :string

    field :surname, :string

    field :age, :integer

  end

  criteria(under: age, where: el.age < ^age)

  criteria(ordered_by: field, order_by: ^field)

end

```

Then create an Ecto Query in one of the following modes:

``` elixir

Person.query(name: "John", under: 18)

```

``` elixir

Person.name("John") |> Person.under(18)

```

This query can then be passed to methods like `Repo.all`.
