Count never accessed files

[scottatchley]

Can you add an option to the file scan tool to detect files in which the mtime is the same as the atime? I am assuming that if mtime == atime, that the file was written (i.e. modified), but never read. If mtime == atime, we want to increment a counter for the bucket of the file size (using whatever buckets the fprof tool is already using). When done, it should print the bucket counts.

What we are trying to determine is the number and size of files that are written and not read.
