Do not warn about missing braces.

I am still very unhappy about what my initializers
look like for vectors and matrices, and inserting all
of the layers of braces needed to make the compiler
happy makes them much, much worse.
Start building Test Fixture facility.
A "Test" is not an "ostringstream"

Convert from inherits-from to contains-a.
Add I/O operations to Suite and Log

Will prefer using these over accessing the "out"
object directly.

Make the Log output stream private.

Add Simple versions of Row, Col, and Mat.

The template versions (where the dimensions are
integer template parameters) were confising CLion.
Implement Test Fixtures

  - add front-end macros (see testing_test.hh)
  - provide "main" function in testing library for main-less tests

Also:
  - during build, redirect test output to proper files
Repair the Test test

The expected text was quoted -- need to quote the
comparison text, too.
