* PolledTimeout Class for wrapping millis() loops
* Add yield policies, improve reset, add host tests
* Fix copyright, comments
* adjust host tests for better time precision
* add fuzzyness to timing tests for CI jitter
* add blink example with polledTimeout
* improve namespace and type naming, add copyright, comments
* fix astyle
* Add valgrind and string tests to host_tests
Valgrind identified an error that was causing intermittent failures in
the host tests, and can check for subtle memory access and allocation bugs.
Add it to the standard host_test suite, and any errors will cause test
failure.
Also start adding string tests, since two undefined behaviors have been
found so far just by inspection.
* Add additional String tests
Looks like a possible bug in the concatenation operator, need to verify
expected behavior.
* Remove verbose from valgrind run
No need to be so chatty on the test. Errors were a little hard to spot.
Go to normal verbosity.
* Add lcov and more string tests
LCOV and genhtml can generate nice HTML coverage charts hilighting test
coverage issues in a much simpler way than gcov text format. Generate these
automatically from gcov output.
Add additional string creation and comparison tests.
* Move String coverage to >50%
Additional string tests and checks
* 66% test coverage in String
* Add allocation-unit-sized strings test
Ensure that strings that are right on the edge of the allocation
size are handled properly and account for trailing 0.
