Duml: Uml diagram generation

[Rikki Cattermole via Digitalmars-d-announce]

Alright so a little project I've put together[0].
Not entirely complete yet. But I feel its at a point where it can be 
announced.

What it does is given a class it'll generate the PlantUML[1] descriptors 
for it. If asked it can call PlantUML itself to generate the image 
version of it.

My plan is to integrate it into Cmsed at some point when it supports 
structs (dvorm models). At which point it'll document properly routes, 
models and any you manually specify.

Object class can be ignored by adding a version if you want it to be.
