Python interface: Add extract methods to MatrixWorkspace to pull out data into numpy

Description

The design document requires adding extract methods to MatrixWorkspace so that data can be pulled out into numpy easily.

There will be 3 methods: extract_x, extract_y and extract_e added to MatrixWorkspace. Note that these will have to copy the data as the memory layout of a 2D numpy array does not match the memory layout of a Mantid workspace.

Refs #4107. Add methods to get data into numpy arrays from a MatrixWorkspace.

There are now read methods that create a 1D read-only numpy array around the existing data spectra and extract methods that pull out all of the data into 2D arrays. They still need profiling.

Revert "Refs #4107. Add methods to get data into numpy arrays from a MatrixWorkspace."

This reverts commit 73d6eb8fab447a2c970218964ae19b0c4c5b19a0. Complex windows errors need fixing first.
