init - new graphics package with some custom made plots (density plots,
normal plots), as well as some tests for the final application.
improved - NaiveLabelling has been improved by adding e.g. total
momentum number calculation.
init - a free theory investigation, using a working second order
symplectic integrator [gnuplotted data verifies second order nature].
improved - utility classes Complex and Combinatorics has added
functions, mainly for faster/more accurate calculation. Added a
combinatoric function for the ladder operator sandwiching of two states.
moved - moved the FockState class to an interacting theory package.
improved - the QFT Sandbox is now more interactive and contains plots.
improved - combinatorics now have the ability of dealing only in
integers (space saving).
bugfix - plots can now be used in JPanels (were 0x0 sized before).
init - added a not-yet-fully-functioning interacting theory state and
interaction hamiltonian.
