evolution_system = "slice" turns on the slice evolver: The initial

data are obtained from an arbitrary slice through an exact solution,
and later the evolution of these data is faked by evolving the slice
and reading off the data (g and K) again.

overwrite_boundary = "exact" overwrites g and K on the boundary with
data from a trivial slice through an exact solution. This may be
useful for testing an evolution or excision algorithm.
