Feature/gridconstruction without ug
I do not see a reason to restrict the createSphere.hh
functionality to UGGrid
users.
I propose to stick to calling the factory as given by the GridFactory
interface which immediately makes it accessible to all grids alike.
Note: This changes the interface of the makeSphere
function which is why I created a feature branch instead of pushing it directly. It no longer takes a grid as input and one needs to specify the grid type explicitly when using the function.
Plan: I intend to merge this feature on 2017-05-10 unless concern or dissent is raised.
