* ENH: Add positivity option for code and dictionary
Provides an option for dictionary learning to positively constrain the
dictionary and the sparse code. This is useful in applications of
dictionary learning where the data is know to be positive (e.g. images),
but the sparsity constraint that dictionary learning has is better
suited for factorizing the data in contrast to other positively
constrained factorization techniques like NMF, which may not be
similarly sparse.
* TST: Test positivity with code and dictionary
Ensure that when the positivity constraint is applied that the
dictionary and code end up having only positive values in the respective
results depending on whether dictionary and/or code are positively
constrained.
* DOC: Positivity constraints dictionary learning
Shows the various positivity constraints on dictionary learning and what
the results of these look like using a Red to Blue color map. These are
included in the examples and also in the docs below dictionary learning.
All of these use the Olivetti faces as a training set.

The LDA accronym for Linear Discriminant Analysis is ambiguous
because of the newly introduced Latent Dirichlet Allocation model.
We therefore deprecate the sklearn.lda.LDA and sklearn.lda.QDA
in favor of explicit names.
