Date recur alpha widget.

There is no particular reason for 'alpha' naming, other than it is the first.

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

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.

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