Hello!

Would it be possible to add a command that does counts the number of
headlines at a particular level in a region or a buffer?

By default the command would count all of the headlines in the buffer or
the region, depending on the selection.  It would also be useful if
prefix arguments restricted the count to headlines at a certain level.

Given the following structure:

 * h1 1
 ** h2 1
 ** h2 2

 * h1 2
 ** h2 3

I would hope for the following behavior from
org-count-headlines-at-level:

 | buffer status          | command         | output      |
 |------------------------+-----------------+-------------|
 | no selection           | no prefix arg   | 5 headlines |
 | no selection           | prefix arg of 1 | 2 headlines |
 | no selection           | prefix arg of 2 | 3 headlines |
 | select the "h1 1" tree | no prefix arg   | 3 headlines |
 | select the "h1 1" tree | prefix arg of 1 | 1 headline  |
 | select the "h1 1" tree | prefix arg of 2 | 2 headlines |

Thanks for considering it!
