[RFC] Array/tests/ScalarAdvection.cpp

[Richard Guenther]

Hi!

The ScalarAdvection.cpp test beyond Array/tests is neither a test, nor an
Array test (it uses the Field abstraction). Ok to either
- move it to the examples directory, beyond Field and a new directory
  ScalarAdvection2
- kill it (seems to be very similar to examples/Field/ScalarAdvection)
- merge/improve it with examples/Field/ScalarAdvection (builds) and
  examples/Field/ScalarAdvection1d (does not build due to old Field
  abstraction)

Any ideas?

Richard.
