Carbon Components is a component library for IBM Cloud

### HTML

The `form` component has been simplified. `.bx--form` has been removed since it was not providing anything significant. Your forms should still be contained in a `<form>` element but the `.bx--form` class is unneeded.
The `.bx--form__row` and `.bx--form__row--column` classes for form layout have been removed. Form styles will no longer dictate default layouts. See HTML docs for more details

The form component supplies 3 classes.
- `.bx--form-item`
- `.bx--label`
- `.bx--form-requirement`

Styles for form components such as `text-input` are contained in their own component files.

For full usage guidelines of the new HTML see the component README file.

### SCSS

The `_form.scss` file is now located at `src/components/form/_form.scss`. You will need to update any `@import` statements for this file to reflect this change.

**New**: 
```scss
@import 'path_to_node_modules/carbon-components/src/components/form/form';
```

**Old**: 
```scss
@import 'path_to_node_modules/@console/bluemix-components/src/components/form/form';
```

Quite a few class names have changed. See table below.
