Vighnesh Birodkar 2f099334f9 MAINT deprecate 1d input arrays for all estimators
Passing 1D arrays to check_array, without setting `ensure_2d` to false now
raises a deprecation warning before reshaping it. This will later throw an
error.

All Scaler classes also throw warnings when 1D arrays are passed.

All unit tests/doctests are modified to ensure that no 1D arrays are passed,
except in explicit 1D array tests where the warnings have been silenced.

Additional tests are also included which check for different 1D array cases.

2D array tests with one samples and one features are also added and where
they failed, `check_array` call has been modified to give a more useful error

Eric Martin ed47b5b744 Directly compute polynomial features.
Polynomial features are computed by iterating over all combinations
of features. For each combination of features, the product of the
columns indexed by the combination is computed.

The fit method is now a no-op, and the transform method works with any
number of features (regardless of what fit was called with).
