  /**
   * Create custom styled checkbox with appropriate bindings and HTML template.
   * You can specify <code><label></code> text with <code>label</code> property, or pass I18n translation key
   * to <code>labelTranslate</code> property. Checkbox specific attributes can be bound in the same way as
   * for Ember.Checkbox <code>checked</code>, <code>disabled</code>.
   * Additional class names can be added with <code>labelClassNames</code> and <code>checkboxClassNames</code>
   * properties.
   *
   * @example
   * Usage:
   * {{view App.CheckboxView checkedBinding="someBinding" label="someLabel"}}
   * {{view App.CheckboxView checkedBinding="someBinding" labelTranslate="i18n.translate"}}
   * {{view App.CheckboxView checkedBinding="someBinding"

   *        checkboxClassNames="class-3 class-4"}}

   * <!-- will append additional markup after <code><label></code> tag
   * {{#view App.CheckboxView}}
   *   <span>Additional content</span>
   * {{/view}}
   *
   * <!-- custom template -->
   * {{#view App.CheckboxView isCustomTemplate="true"}}
