### HTML

Detail Page Header now includes Overflow Menu and Breadcrumb.
A lot of classes have been removed, see SCSS for more details.

### SCSS

The `_detail-page-header.scss` file is now located at `src/components/detail-page-header/_detail-page-header.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/detail-page-header/detail-page-header';
```

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

A lot of classes have been changed and consolidated.
There are no direct 1:1 class name changes, but a lot of classes have been removed.
