Faster interpolation

Interpolation to a structured grid is now faster, so now the .contains() is the bad guy.

Default:
da.interp_like(grid)

Faster with extrapolation everywhere:
da.interp_like(grid, extrapolate=True)

Faster with limited extrapolation:
da.interp_like(grid, extrapolate=True, radius=0.1)

Will close #413

Just a comment on the last option:

Faster with limited extrapolation: da.interp_like(grid, extrapolate=True, radius=0.1)

I think using a small radius can cause nan results within the mesh boundary in places where you would expect there to be a value. I tried this with a mesh that had an average element size of 5m2, interpolating to a 1m x 1m grid, and the result came out as almost entirely nan.
