This is a basic implementation of error logging using the limited
facilities provided by Google Analytics.
Errors within the Angular app itself will be handled by a new
`ReportingErrorHandler` service, which overrides and extends the
built-in `ErrorHandler`.
Further, errors outside the app, which arrive at `window.onerror`
will also be reported to Google Analytics.

is undesirable and confusing. All sub-menu toggles should have no other
effect than expanding/collapsing the corresponding sub-menu.

Previously searching for `compose` did not include `Validators`
in the search results because we were not including all the
`static` members of API docs in the index.
