Updating help for sdpsettings
Removed dead code
Allow matrix arguments in slog.m. Closes #49
Handle the case when gurobi/cplex returns error code 12, i.e., not sure whether feasible or unbounded
Trying to speed up recursive computation of derivatives. First level of eval-based operators can be moved outside general logic since all arguments are linear.
More exploitation of structure in recorsive differentiation by treating purely bilinear levels specially
Removed dead code
Added extra cut on convex envelope approximation
Support forced selection for solver despite analysis (used in bilinearly parameterized optimizer objects)
Cleaned up definition of CPLEX solvers (one gateway to lp/qp/socp variants)
Closes issue #50
Generic fix for nonlinear operator applied to sparse matrix. Closes #51
Remove factor info on nonlinear operators. Never used anyway
Removed dead code
Bail out early if no factors
Fixes #52
Closes #54
Closes #53
Added a display of number of branched variables
Added support for timing information from various steps in the global solver
