/**
* Entry point of the Form component.
*
* Use this class to conveniently create new form factories:
*
* <code>
* use SymfonyComponentFormForms;
*
* $formFactory = Forms::createFormFactory();
*
* $form = $formFactory->createBuilder()
* ->add('firstName', 'text')
* ->add('lastName', 'text')
* ->add('age', 'integer')
* ->add('gender', 'choice', array(
* 'choices' => array('m' => 'Male', 'f' => 'Female'),
* ))
* ->getForm();
* </code>
*
* You can also add custom extensions to the form factory:
*
* <code>
* $formFactory = Forms::createFormFactoryBuilder()
* ->addExtension(new AcmeExtension())
* ->getFormFactory();
* </code>
*
* If you create custom form types or type extensions, it is
* generally recommended to create your own extensions that lazily
* load these types and type extensions. In projects where performance
* does not matter that much, you can also pass them directly to the
* form factory:
*
* <code>
* $formFactory = Forms::createFormFactoryBuilder()
* ->addType(new PersonType())
* ->addType(new PhoneNumberType())
* ->addTypeExtension(new FormTypeHelpTextExtension())
* ->getFormFactory();
* </code>
*
* Support for the Validator component is provided by ValidatorExtension.
* This extension needs a validator object to function properly:
*
* <code>
* use SymfonyComponentValidatorValidation;
* use SymfonyComponentFormExtensionValidatorValidatorExtension;
*
* $validator = Validation::createValidator();
* $formFactory = Forms::createFormFactoryBuilder()
* ->addExtension(new ValidatorExtension($validator))
* ->getFormFactory();
* </code>
*
* Support for the Templating component is provided by TemplatingExtension.
* This extension needs a PhpEngine object for rendering forms. As second
* argument you should pass the names of the default themes. Here is an
* example for using the default layout with "<div>" tags:
*
* <code>
* use SymfonyComponentFormExtensionTemplatingTemplatingExtension;
*
* $formFactory = Forms::createFormFactoryBuilder()
* ->addExtension(new TemplatingExtension($engine, null, array(
* 'FrameworkBundle:Form',
* )))
* ->getFormFactory();
* </code>
*
* The next example shows how to include the "<table>" layout:
*
* <code>
* use SymfonyComponentFormExtensionTemplatingTemplatingExtension;
*
* $formFactory = Forms::createFormFactoryBuilder()
* ->addExtension(new TemplatingExtension($engine, null, array(
* 'FrameworkBundle:Form',
* 'FrameworkBundle:FormTable',
* )))
* ->getFormFactory();
* </code>
