Add new file types to .gitignore
Add missing function call in MathTest
Fix grammar error
Mention the math unit testing exercise in README
Change PHPUnit command used in HOWTO-TESTS
We now have more than one test case, which means lots of failing
tests, whereas the HelloWorldTest case has one failing, and one
passing. This means less command line noise, so easier understanding.
Set the standard number of blank lines before class declarations
Add tutorial files for getting started with unit testing
Add coding standards document
Update README with short description for the second step
Set up infrastructure for automated tests
Please note that phpunit.xml is configured so that test reports
are generated in the tests/reports directory. This is why I had
to add this directory to .gitignore. We don't want test reports
tracked by Git.
Add space after links in README
The GitHub parser interpreted the ")" char as being part of the link.
Add pseudo-guide for setting up Git
Add README file
