add more examples and tests

[chriscoey]

fixes #328 fixes #334 fixes #319 fixes #322

[chriscoey]

so far, only added gate sizing example from cvx (hard-coded, convex.jl). next I will add a version of Ising model problem (also convex.jl).

gate sizing solves easily yet is non-trivial, so it is a good test. i will but into cbf and into tests

gatesizing test now used for both NLP and conic solvers, passes!

[chriscoey]

nearly finished Ising

[chriscoey]

nice thing is that Ising can be mixed-SOC-Exp depending on which options you use

[chriscoey]

unfortunately generating Ising data was a huge pain, so i left it out of examples and just added one MPB format test.

I have added a cardinality constrained least squares problem, in both MIQP and MISDP forms (equivalent). Have not tested the MIQP part yet because need #336

[chriscoey]

oh woops yes i will remove others.jl that was just staging

[chriscoey]

still need to add the MISDP, MIQP, converted MIQP to tests

[chriscoey]

bug in something I changed in transform function was exposed by zero cone test so I'll have to look at the diff
