Joel Nothman 8570622a44 [MRG+1] DOC insert spaces before colons in parameter lists (#7920) 
* DOC insert spaces before colons in parameter lists

Complies with numpydoc to improve rendering and automatic quality
assurance such as #7793. Affects listings of Parameters Attributes,
Returns.

Performed with the help of:

    grep -nE '^(    )+[a-zA-Z][a-zA-Z0-9_]*: ' sklearn -R | grep -v -e
    externals -e tests | grep -v -e default: -e else: -e Warning: -e Note:

Ekaterina Krivich 02cc6f5d3a [MRG] TST Ensure __dict__ is unmodified by predict, transform, etc (#7553) 
* Add test for __dict__ for estimator checks

  check that "predict", "transform", "decision_function" or
"predict_proba" methods do not change the state of __dict__ of any
estimator

  see #7297

* Add a test to test_check_estimator

  that shows that check_estimator fails on an estimator that violates this

* Fixed bug where NMF's n_iter_ attribute was set by calls to transform
