sub-module support

[Saravanan Shanmugham (sarvi)]

The code base is quite large and not being able to work with it in a
modular fashion, would mostly likely be a deal breaker for us. Atleast
for immediate adoption. 

Is there a reason why the forest extension Is not being considered for
standardization. That seems very similar to git sub-module and close
what we are looking for. Is there any possibility this feature could
become part of 1.0?

     I plan to make something much like Forest part of the 
     core, but it will be post-1.0.
