reflect function statements into 'window' object.  i have checked that
firefox does this.
this test works now
really hackish, prototype support for exclude paths
utility to use Eclipse to find JS prologue files for analysis
add prologue files explicitly, which is now needed
reuse util support for building scopes
no longer add prologue files implicitly, since this code cannot always
find them now that we allow all kinds of prologues to be used
more flexible eclipse project paths and engines for javascript to
support adding different model JS files as prologues.
remove now-unused functionality
adapt to new engine infrastructure.  updated test zip file.
