Issue multiplying expressions with matrices

1

The following code produce an error when multiplying a Matrix{Float64} with a vector with MultiplyAtoms ``` julia m = Variable(3) g = randn(3) F = Array(typeof(m[1]*g[1]),3) for i = 1:3...

Replace gebal! with GenericSchur.balance! in matrix_comps

make feedback differentiable by avoiding try-catch

Zygote.jl does not handle try-catch, so I modified `feedback` slightly to avoid using it, but maintained the useful error messagees. The comment `# inv seems to be better than lu`...

`hinfnorm` fails occasionally and it would be nice to come up with better default values for the tolerances etc. ```julia success = map(1:10000) do i G = ssrand(1,1,4) try hinfnorm(G)...

Deprecate function pole and rename to poles
