Generate a suitable form input for a given method by performing introspection on the type.

 Options:

 * :as         - override the default type used (:url, :email, :phone, :password, :number, :text)
 * :label      - override the default label used ('Name:', 'URL:', etc.)
 * :error      - override the default error used ('invalid', 'incorrect', etc.)
 * :input      - add custom options to the input ({ :class => 'goregous' }, etc.)
 * :container  - add custom options to the container ({ :class => 'gorgeous' }, etc.)

 Usage:

   f.input(:name)
   f.input(:email)
   f.input(:password_a, :label => "Password", :hint => "It's a secret!", :container => { :class => "half" })
   f.input(:password_b, :label => "Password", :hint => "It's a secret!", :container => { :class => "half" })

 Equivalent:

   <div class="block name">
     <%= f.label(:name)
     <div class="input string"><%= f.text_field(:name)</div>
      <div class="error">...</div>
   </div>
   <div class="block email">
     <%= f.label(:email)
     <div class="input string"><%= f.email_field(:email)</div>
      <div class="error">...</div>
   </div>
   <div class="block half password_a">
     <div class="input">
       <%= f.label(:password_a, "Password")
       <%= f.password_field(:password_a)
       <div class="hint">It's a secret!</div>
       <div class="error">...</div>
     </div>
   </div>
   <div class="block half password_b">
     <div class="input">
       <%= f.label(:password_b, "Password")
       <%= f.password_field(:password_b)
       <div class="hint">It's a secret!</div>
       <div class="error">...</div>
     </div>
   </div>
