Fixed a bug in zero equation detection
Finds matrix T for which Tq(:) equals U q V^T, where U,q,V are matrices
optimized for speed
Utils for computing accuracy of solutions, etc
Various changes to support dual recovery
Big revamp.  Added support for dual recovery. Changed the way
conjugations are computed. All tests pass
Initial check in
"better" construction of DD extreme rays
Added support for non-rectangular matrices
Converted multiple solve methods into a single  method with options.
Optimized method for making a matrix from submatrices in 2x2 case
Formatting/capitalization of method names
Use a common "Reduce" function for primal and dual problems. Use
LPSolver wrapper.
Added default solver option (remove dual equations defaults to yes)
Tweaked tolerances
