ENH : speed up f_regression
FIX : array copy for compat pb
DOC typos, line-width and minor stylistic fixes in pipeline module
COSMIT shallow copy of steps in Pipeline + code style
fast tree prediction based on mystic cython kung-fu
cosmit
staged_predict for regression
test for staged predict and cosmit
more test cases
more test cases (input check at prediction time, degenerate inputs)
use approriate data types (Py_ssize_t)
better input checks at prediciton time
ENH: Added p to classes in sklearn.neighbors

Added keyword p to classes in sklearn.neighbors to specify an arbitrary
Minkowski metric for nearest neighbors searches. Implements issue #351
TEST: tested different p values in nearest neighbors
DOC: Documented p value in nearest neighbors
DOC: Added mention of Minkowski metrics to nearest neighbors.
Fix doctest failure.
Merge branch 'nearest_centroids' of https://github.com/robertlayton/scikit-learn into nearest_centroids
Fix doc mistakes.
Precomputed distance matrices can be rectangular.
