I had a go at it, and I have something for that now. This graph 
should show what std.regex imports. I'm not sure if anything is 
missing from the module info. I imagine there's a template which 
might need insantiating first in order to add in import line, and 
I'm not sure if the ModuleInfo will include all the scoped 
imports or not. I assume it does.

I added an extra method named 'addModuleWithDirectDepdencies' for 
adding a module to the set of modules and just its direct 
dependencies, not the transitive dependencies. Then I added an 
extra set to the structure for tracking which modules are 
supposed to be leaf nodes in the graph, and made the DOT 
functions check for that.

I had to add the leaf checking, as the dependencies could be 
importing each other, and the structure was only storing nodes, 
not edges. I should maybe make the structures store just a 
directed graph, but whatever.
