adding tests for features to come
Early matrix/vector support

a reimplemetation of the numpy matrix class, with:
 - slightly different printing
 - convenient element-wise functions
 - overloaded <= for constraint generation

swapping out lambdas
more vector and constraint tests
Switched to arrays
simplified simplify, new equality checking
more nomials refactoring

 - new equalities (now eid- and c- instead of string-based)
 - cleaner and faster simplify code
 - use of defaultdicts for eid (means that any non-named variables returns
   a 0 instead of an error)
 - removed non-dict interface to making a monomial
switched matrix tests to arrays
changed tests to match dictionary interface
small error
small fixes
Added Mosek CLI interface, but it's no faster than CVXopt
MOSEK support! Not as fast as hoped
Fixed what look like two debug-era remnants

both the example MOSEK dgopt and expopt interfaces had a place where they
would print runtime info to stdout via printf instead of using the task's
special stream function.
updated expopt library binary
