Material design: [Text fields](https://www.google.com/design/spec/components/text-fields.html)

`<paper-input>` is a single-line text field with Material Design styling.

    <paper-input label="Input label"></paper-input>

It may include an optional error message or character counter.

    <paper-input error-message="Invalid input!" label="Input label"></paper-input>
    <paper-input char-counter label="Input label"></paper-input>

It can also include custom prefix or suffix elements, which are displayed
before or after the text input itself. In order for an element to be
considered as a prefix, it must have the `prefix` attribute (and similarly
for `suffix`).

    <paper-input label="total">
      <div prefix>$</div>
      <paper-icon-button suffix icon="clear"></paper-icon-button>
    </paper-input>

A `paper-input` can use the native `type=search` or `type=file` features.
However, since we can't control the native styling of the input (search icon,
file button, date placeholder, etc.), in these cases the label will be
automatically floated. The `placeholder` attribute can still be used for
additional informational text.

    <paper-input label="search!" type="search"
        placeholder="search for cats" autosave="test" results="5">
    </paper-input>

See `Polymer.PaperInputBehavior` for more API docs.

### Focus

To focus a paper-input, you can call the native `focus()` method as long as the
paper input has a tab index.

### Styling

See `Polymer.PaperInputContainer` for a list of custom properties used to
style this element.
