IndexedVector doesn't work if Type isn't a Number

[IainNZ]

Makes collecting all variables coefficients together not work.

Could you give an example of how you'd like to use it?

[IainNZ]

IndexedVector(GenericAffExpr{Float64, Uncertain}, m.numCols)
which I'd use for a
GenericAffExpr{GenericAffExpr{Float64, Uncertain}, Variable}

[mlubin]

This should work now, you just need to implement zero(GenericAffExpr{Float64, Uncertain}) to return an empty expression. Don't forget to remove duplicates in each GenericAffExpr after you remove duplicates in the GenericAffExpr{GenericAffExpr} :)

Oh happy day :)
