203477c3a8 First shot at periodicity congruences 
Verification of Przytycki's congruence works fine, however there are
some small modifications that could be made.

The, naive, approach to the verification of periodicity congruence for
the Khovanov polynomial didn't work. There are just too many cases to
check. Generation of all of them can exhaust the memory.

ad0f60f5c0 Renamed driver kk. Added support for various invariants (gss + kh, 
lsss, leess, sq2, s) to prepare for release of the link splitting
spectral sequence paper on the arXiv.

a09ca308d9 Added mod_map::graded_piece. Friendlier (but not completely friendly) 
compute_forgetfulss function in main.cpp.

9ee5950195 Some changes to algebra/ to make kernel, image and quotient work over 
PID.  Goal: compute spectral sequences over PID.  Updated main to
compute Lee Z/2 bound.

crossings.

3797868325 Fixeds to module reader (not carry unnecessary refcounts?). main 
checks for homotopy type differences.  Added planar_diagram::{show,
display}_knottheory.

a0f94aad47 Fixed bug in writer::write_mod. Added (partial) support for comparing 
sq1/2 to main.

417fe1ea4d Added io support for module, linear_combination, mod_map and grading. 
Added intersection and sum for free_submodule.  Modified mpimain to
dump cohomology, sq1 and sq2 as objects (instead of poincare series).

50a2438996 Added Roberts' totally twisted Kh differential to 
spanning_tree_complex.  Main set up to compare twisted E3, twisted Kh
and normal Kh.

b337bd36ac mod_map is now just a wrapper for a map implementation. mod_map is 
now functional.  Added map_builder classes for imperatively
construction maps.  Initial collection of map implementations
(explicit, zero, 1, and composition.)

4443c8e331 Replaced laurentpoly with multivariate_laurentpoly and updated uses 
(sseq, module) appropriately; removed algebra/laurentpoly.h and added
algebra/multivariate_laurentpoly.h.  Added io, muladdeq to Z.  Added
functions open_file, close_file to lib/io.h.  Added operator < to
map_wrapper.

5d4acb7a86 Added /serial.cmd* to .gitignore. Minor changes to build with version 
of gcc on newcomp.  Use global reference (::) in linear_combination*
typedefs in ring classes.  Renamed linear_combiation::set set_coeff.
