FR: count headlines at a level in a region

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!

May I ask why do you need this?  

Knowing about the context of use for such a function would help figure
out how to write it.

If you just need to know the number of headlines occasionnally, then: 

  C-c C-x b          will open an indirect buffer
  M-x occur "^\*+ "  will find all headlines

But I guess you need to re-use the output of such a function somehow.
