     * Parses the request URL into a `ParsedUrl` object.
     * Parsing depends upon certain values of `config`: `apiBase`, `host`, and `urlRoot`.
     *
     * Configuring the `apiBase` yields the most interesting changes to `parseUrl` behavior:
     *   When apiBase=undefined and url='http://localhost/api/collection/42'
     *     {base: 'api/', collectionName: 'collection', id: '42', ...}
     *   When apiBase='some/api/root/' and url='http://localhost/some/api/root/collection'
     *     {base: 'some/api/root/', collectionName: 'collection', id: undefined, ...}
     *   When apiBase='/' and url='http://localhost/collection'
     *     {base: '/', collectionName: 'collection', id: undefined, ...}
     *
     * The actual api base segment values are ignored. Only the number of segments matters.
     * The following api base strings are considered identical: 'a/b' ~ 'some/api/' ~ `two/segments'
     *
     * To replace this default method, assign your alternative to your InMemDbService['parseUrl']
