Changed to ignore example folders.
Flatten cell ids before using.

Fixed
-----
* Flatten cell_ids array. This fixes a problem where if the array is 0D,
  it can not be squeezed along axis=1.
Fixed typecasting error.

Fixed
-----
* The ufunc, around, was producing a float array but was passed an int
  array for output.
Use floats for testing data.
Removed print statements.
Run unit tests with nosetests and landlab.test().
Merge remote-tracking branch 'upstream/master' into fix-landlab-test

Moved drivers into examples folder.

Moved
-----
* Moved driver modules into the examples folder so that they are not run
  when the unit tests are run.
Import tested classes/functions into doctests.

Changed
-------
* Import all classes, functions, etc. that are used in doctests. Apart
  from being clearer, this allows more robust testing.
Added defaults for test method.
