What new or enhanced feature are you proposing?
Within the codegen, there are many header/library files in Javascript that
are identical and created on each codegen pass.

These header/library files should be extracted out of the templates and
moved into a separate library.

The individual library itself could be specified in a similar method to
symfony projects, e.g. setting up an alias in Apache ('/sf') pointing to a
library folder ('/var/sf/web/')

What goal would this enhancement help you achieve?
These files would no longer have to be formatted on every codegen pass, and
it would help with testing ( issue 74 ).
