  PEC (Perfect Electric Conductor): Reflects all waves perfectly
  ABC (Absorbing Boundary Conditions): Absorbs all waves
 
- -L(self, boundary_type="ABC"): Sets the left boundary condition.
- -R(self, boundary_type="ABC"): Sets the right boundary condition.
- -B(self, boundary_type="ABC"): Sets the backward boundary condition.
- -F(self, boundary_type="ABC"): Sets the forward boundary condition.
- -D(self, boundary_type="ABC"): Sets the down boundary condition (for 3D grids only).
- -U(self, boundary_type="ABC"): Sets the up boundary condition (for 3D grids only).
- A short example: <code>
+ - L(self, boundary_type="ABC"): Sets the left boundary condition.
+ - R(self, boundary_type="ABC"): Sets the right boundary condition.
+ - B(self, boundary_type="ABC"): Sets the backward boundary condition.
+ - F(self, boundary_type="ABC"): Sets the forward boundary condition.
+ - D(self, boundary_type="ABC"): Sets the down boundary condition (for 3D grids only).
+ - U(self, boundary_type="ABC"): Sets the up boundary condition (for 3D grids only).
+ A short example:
+ <code>
  boundaries = Boundaries(3) # Creates a 3D grid with default ABC boundaries
  boundaries.L("PEC") # Sets the left boundary to PEC
  boundaries.R("PEC") # Sets the right boundary to PEC
