Mitchell Hanberg 1a5837d1b7 Components API
Components work very similarly to how they worked before, but with a few
differences.

To define a component, you can create a file in your configured temple
components directory, which defaults to `lib/components`. You would
probably want ot change that to be `lib/my_app_web/components` if you
are building a phoenix app.

This file should be of the `.exs` extension, and contain any temple
compatible code.

You can then use this component in any other temple template.

For example, if I were to define a `flex` component, I would create a
file called `lib/my_app_web/components/flex.exs`, with the following
contents.

```elixir
div class: "flex #{@temple[:class]}", id: @id do
  @children
end
```

And we could use the component like so

```elixir
flex class: "justify-between items-center", id: "arnold" do
  div do: "Hi"
  div do: "I'm"
  div do: "Arnold"
  div do: "Schwarzenegger"
end
```

We've demonstated several features to components in this example.

We can pass assigns to our component, and access them just like we would
in a normal phoenix template. If they don't match up with any assigns we
passed to our component, they will be rendered as-is, and will become a
normal Phoenix assign.

You can also access a special `@temple` assign. This allows you do
optionally pass an assign, and not have the `@my_assign` pass through.
If you didn't pass it to your component, it will evaluate to nil.

The block passed to your component can be accessed as `@children`. This
allows your components to wrap a body of markup from the call site.

In order for components to trigger a recompile when they are changed,
you can call `use Temple.Recompiler` in your `lib/my_app_web.ex` file,
in the `view`, `live_view`, and `live_component` functions

```elixir
def view do
  quote do
    # ...
    use Temple.Recompiler
    # ...
  end
end
```
