-    direct_sum(traj1::NamedTrajectory, traj2::NamedTrajectory)
-
-Returns the direct sum of two `NamedTrajectory` objects.
-
-The `NamedTrajectory` objects must have the same timestep. However, a direct sum
-can return a free time problem by passing the keyword argument  `free_time=true`.
-In this case, the timestep symbol must be provided. If a free time problem with more
-than two trajectories is desired, the `reduce` function has been written to handle calls
-to direct sums of `NamedTrajectory` objects; simply pass the keyword argument `free_time=true`
-to the `reduce` function.
-
-# Arguments
-- `traj1::NamedTrajectory`: The first `NamedTrajectory` object.
-- `traj2::NamedTrajectory`: The second `NamedTrajectory` object.
-- `free_time::Bool=false`: Whether to construct a free time problem.
-- `timestep_name::Symbol=:Δt`: The timestep symbol to use for free time problems.
