Description

Add MATLAB support for reading numeric types (i.e. [u]int[x][y], float, double) from Feather files. This is the first in a series of future feature submissions for Feather read/write support and other Arrow IPC integration with MATLAB.

The associated pull request creates a top-level "matlab" directory in the Apache Arrow project. It also introduces a MATLAB function "featherread", which takes a Feather filename as input and returns a MATLAB table. featherread maps Feather datatypes to corresponding MATLAB datatypes.

This initial pull request does not support null values.

featherread.m calls the Arrow C+ APIs using MEX, MATLAB's facility for calling C/C+ code.

See the README.md in the "matlab" directory for instructions on how to build the MEX interface. Currently, building on Windows using CMake is not fully functional, but the MEX interface can be compiled manually using the MATLAB "mex" command.

A MATLAB install is required to be present on your machine to build the MEX interface.
