Path between functions...

Hi,

Using the Function Calls display is really nice.. But sometimes I want  
to know if there is a path leading from one function to another. And  
trying to track that down from the Function Calls display can be  
tedious and error prone.

So here is a quickie that I just whipped up. Doesn't do the nice  
things that the Function Calls display can do -- like double-clicking  
to highlight the code in the editor. But it does show me what I needed  
to know. And in some rather large projects, this can be a life saver...

The pic below (hopefully it passes the censors) shows the result of  
executing:  (path-between #'connect-to-database #'rollback)
