Miller regression tests

There are a few files unit-tested with Go's testing package -- a few dozen cases total.

The vast majority of Miller tests, though -- thousands of cases -- are tested by running scripted invocations of mlr with various flags and inputs, comparing against expected output, and checking the exit code back to the shell.

How to run the regression tests, in brief

Note: while this README.md file is within the test/ subdirectory, all paths in this file are written from the perspective of the user being cd'ed into the repository base directory, i.e. this directory's parent directory.
