======
* Small cleanups in Molecule interface

* Spacing related elements perform suicide after calculating
distances.  This saves a some memory, approximately 2 to 5 % ?

* Small cleanups in line breaking: Paper_column stores springs and
rods in only one place now.  All fields relating to energy have been
removed

* Don't generate all output Scheme in memory, but evaluate to output
file immediately.  This will reduce memory usage a little.

* Use STL's map  for Dictionary template

* Substitute pointers on element properties of the root Line_of_score
as well.

* Added toplevel doc target, to support building doc with --srcdir
