// # Global Header Component
// Implements the [Global Header design pattern](https://www.lightningdesignsystem.com/components/global-header) in React.
// Based on SLDS v2.1.0-rc.2
// ## Dependencies
// ### React
import React from 'react';
import PropTypes from 'prop-types'; // This component's `checkProps` which issues warnings to developers about properties when in development mode (similar to React's built in development tools)

import checkProps from './check-props';
import componentDoc from './docs.json'; // ### Event Helpers

import EventUtil from '../../utilities/event'; // ## Constants

import { GLOBAL_HEADER, GLOBAL_HEADER_PROFILE, GLOBAL_HEADER_SEARCH, GLOBAL_HEADER_TOOL } from '../../utilities/constants';

 * The global header is the anchor for the Salesforce platform and spans all other parts of the UI. It accepts children to define the items displayed within.

 * ```
 * <SLDSGlobalHeader>

 *   <SLDSGlobalHeaderButton />
 *   <SLDSGlobalHeaderDropdown />
 *   <SLDSGlobalHeaderDropdown />
 *   <SLDSGlobalHeaderProfile />
