dstats reborn

[John Colvin via Digitalmars-d-announce]

David Simcha's stats library is full of useful code and it was a 
shame to let it rot. I've patched it up to work with modern D 
compilers and added dub support.

I have also made a pull request to David's repository to 
integrate these changes. If they are merged there then I'll 
redirect the dub respository and add a link in the readme on my 
github fork.
