Date recur opening hours widget.

The codename 'oscar' is used because it was designed for 'Opening hours'

This is a widget built with Drupal states in combination with light sprinkle of CSS.

Date range always occurs on the same day, the range cannot spread across multiple days. An all-day option is provided.

Frequencies and parts are designed to be inaccessible or temporarily invisible or if field level frequency/part configuration dictate it.

It supports the following modes:

Non recurring.
Multiday.
Weekly:
- hard coded interval of 1. Or 2 if fortnightly is chosen.
- with optional expansion to multiple weekdays.
- with optional occurrence limitation by date or count.
Monthly:
- hard coded interval of 1.
- with optional expansion to multiple weekdays.
- with optional limiter on ordinal.
- with optional occurrence limitation by date or count.
