/**
 * React introduced additional lifecycle methods in v16 for capturing errors
 * that occur in a specific sub-tree of components. This component helps to
 * consolidate some of the duplication that occurs when using these lifecycle
 * methods across a codebase. In addition, it allows you to specify the fallback
 * UI to display when an error occurs in the sub-tree through the `fallback`
 * prop.
 *
 * This component roughly follows the React.js docs example code for these
 * methods. In addition, it takes advantage of an `ErrorBoundaryContext` so that
 * consumers can specify their own logic for logging errors. For example,
 * reporting an error in the UI to an external service for every `ErrorBoundary`
 * used.
