Code assumes coords start at zero

[lionfish0]

Found on line 36 in AdvectionDiffusionModel constructor:

        #coords is a D x (Nt,Nx,Ny) array of locations of the grid vertices.
        #TODO Maybe write more neatly...
        tt=np.linspace(0.0,self.boundary[1][0],self.resolution[0])
        xx=np.linspace(0.0,self.boundary[1][1],self.resolution[1])
        yy=np.linspace(0.0,self.boundary[1][2],self.resolution[2])
        self.coords=np.asarray(np.meshgrid(tt,xx,yy,indexing='ij'))

Line 38 in 182a7c4

tt=np.linspace(0.0,self.boundary[1][0],self.resolution[0])

The linspace presumably shoundn't start at 0?

Need to write a unit test for boundary.
