Keep in mind that Project and File ARE targets. Of course, Project 
doesn't have to be either (as in the current implementation, i.e. 
projects are not "actualized" into Jam targets).

What we might really have here is

Project (not a Target)
FileMetaTarget (cf. MainTarget) (not a Target)
FileTarget <- Target
AliasTarget <- Target
etc...

This is actually similar to the current implementation except

o no "abstract-target" heirarchy
o no "basic-target" for alternatives
o "project" and "project-target" a single class
o "virtual-target" = "Target"
o build an explicit graph of Target rather than pass around lists of 
"virtual-target"
o ...
