docs: Creates a new Places Autocomplete request for a given input. The Place Autocomplete service can
  match on full words as well as substrings. Applications can therefore send queries as the user
  types, to provide on-the-fly place predictions.
  
  @param context The context on which to make Geo API requests.
  @param input input is the text string on which to search.
  @param sessionToken Session token, to make sure requests are billed per session, instead of per
  character.
  @return Returns a PlaceAutocompleteRequest that you can configure and execute.
