- also PackedBoolList.get(x) == 1 can be written without the ==
  comparison since the unsigned -> bool conversion is fast

- exception calcType.H since it'll most likely be used for building
  applications anyhow

- use quailified names in more of the lagrangian code

- killed some tab indents in various places.

- new members:  capacity(), two-argument resize()/setSize(), const storage()
- new static members: max_value(), packing(), etc.

- can use 'XX.empty()' instead of 'XX.size() == 0', 'XX.size() < 1' or
  'XX.size() <= 0' or for simpler coding.
  It also has the same number of characters as '!XX.size()' and /might/ be
  more readable

- many size checking had 'XX.size() > 0', 'XX.size() != 0', or 'XX.size() >= 1'
  when a simple 'XX.size()' suffices
