Count of open tasks on page

[gwagner2]

Is it possible for Dataview to return a count of open tasks on a page?

For example when taking meeting notes in one page where multiple tasks could be littered throughout the note. It would be nice to have a summary at the top that states how many open tasks are on the page.

At a glance, maybe

`= sum(map(this.file.tasks, (t) => choice(t.completed, 1, 0)))`

Close, but this shows closed tasks just negate the t.completed to make it show open tasks
