fixed comments; default value of pos_mf_steps set to 50 in estimate_likelihood
the number of test samples does not have to be the exact multiple of batch_size
Minor changes.
Merge branch 'master' into norb
pep8, added image_shape class parameter to datasets/norb.py
pep8 cleanup. datasets/dataset.py, datasets/dense_design_matrix.py and utils/__init__.py are now pep8-clean.
commit before switching branches
Coded up tests, need to pylint and run them.
commit before exploring earlier commits for the origin of the weird pylint error in utils/__init__.py
Committing before maybe changing *format_as() methods to support converting to/from sparse and non-sparse. This will also require changes to how those functions call np_validate() to sanity-check the input batch.

commit before attempting to implement a reshape() for SparseVariable
Commit before attempting to support VectorSpace.format_as(sparse_variable, composite_space).
minor fix
commit before removing format_as / np_format_as dichotomy. If people object to the API change, we can always trivially add it back in. But for now, the two functions are often implemented by duplicating long stretches of code. Better to have a single function with a single chain of logic, that internally switches on the type of the batch (theano symbol, numpy ndarray, or scipy.sparse array) selectively, only on lines that necessitate making such distinctions.

commit before making get_expected_error recursive
simplified composite dtype treatement
Add iPython Notebook tutorial about hyperparameter optimization using Jobman
Few changes to the tutorial
