Root file for pure Isabelle: all modules in proper order for loading
Loads pure Isabelle into an empty database.

To build system, use Makefile (Poly/ML) or Makefile.NJ (New Jersey ML)

TO DO: 
instantiation of theorems can lead to inconsistent sorting of type vars if
'a::S is already present and 'a::T is introduced.
