Helper struct for testing basic control systems.
To signify which control systems you want, set the corresponding DerivOrder. To turn control systems off, put 0 for their DerivOrder in the templates of the metavariables.
Ideally we'd construct the runner here and just pass that to the test to simplify as must of the work as possible, but MockRuntimeSystems aren't copy- or move-able so we have to make the necessary info available. The simplest way to do this was to have functions that return references to the member variables.

Actually run the control system test.
The horizon_function should return a std::pair<ylm::Strahlkorper<Frame::Distorted>, ylm::Strahlkorper<Frame::Distorted>> representing the two horizons in the grid frame. This means the user is responsible for doing any coordinate transformations inside horizon_function as this function won't do any. The number_of_horizons is used to determine if we actually use both horizon "measurements" as some control systems may only need one. If only one horizon is used, the default is to use AhA.
For the basic control systems, a common function is defined for you: control_system::TestHelpers::build_horizons_for_basic_control_systems().

Setup the test.
The function initialize_functions_of_time must take a const gsl::not_null<std::unordered_map<std::string, std::unique_ptr<domain::FunctionsOfTime::FunctionOfTime>>*> for the function of time map, a const double for the initial time, and a const std::unordered_map<std::string, double>& for the expiration times. This function will initialize the functions of time and must return a double that represents the radius of the excision spheres. Some existing functions are given in the control_system::TestHelpers namespace for Expansion, Rotation, and Translation.
