Separating out the spot optimization classes
prepping update
New data structure in between user and SDP representation.
Simple abstract class for solvers.
Moving things around for new separation of sdp and solver.
added ignore file for MAC compilation products
broke up solving from SDP problem representation. Support for SeDuMi right now.
renamed spotprog
new solvers, switched to mixed primal / dual representation for sdps
a little bit of cleanup
more exclusions of compliation products
simple tests, not at all exhaustive
simple todo list
updating solver interface.
Small errors left behind in switching to handling dual form.
Basic spotprog support, layer between raw conic program and user.
todo file
Added rotated lorentz cone support and tests.  New functions for accessing constraint descriptions.
approximation of SDP by SDD.  Also conversion of program to dual.
removed some old files
