Time integration

The following options are available for time integration:

using LevelSetMethods
subtypes(LevelSetMethods.TimeIntegrator)

3-element Vector{Any}:
 ForwardEuler
 RK2
 RK3

These are all explicit schemes, and therefore a sufficiently small time step, dependant on the LevelSetTerm being used, is required to ensure stability. We recommend using the second order RK2 scheme for most applications.
