Views Filter handler for Open/Closed (today/now/soon) [D7]

Many of the module that use the Date API allow for filtering content based on the dates. Example, filter all content that occurs in the future, or between these dates.

For this module, I would like to be able to filter on things such as is the node open today, currently (the current time is between the open and close times), or will be opening/closing in the next 'x' hours.
