Class VariableCoefficientAdvectionOperator

A class for space- and time-dependent DG-advection operators.

`advec_v` is a callable expecting two arguments `(x, t)` representing space and time, and returning an n-dimensional vector representing the velocity at x. `bc_u_f` is a callable expecting `(x, t)` representing space and time, and returning an 1-dimensional vector representing the state on the boundary. Both `advec_v` and `bc_u_f` conform to the `hedge.data.ITimeDependentGivenFunction` interface.
