As I already mentioned in the #35 issue, I think it's more suitable to use a PHP build tool instead of a JS one. I don't tell that Grunt is not a powerful tool but it's a complicated installation process to be able to run tests.
Phing is required as a composer package and can be run directly after the composer install.
Examples:
```
vendor/bin/phing
vendor/bin/phing test
vendor/bin/phing clean
vendor/bin/phing phplint
vendor/bin/phing phpcs
vendor/bin/phing phpunit
vendor/bin/phing phpunit -Donly.units=true #The travis test process
```
The only difference here is the watch process. Phing doesn't have that kind of feature. It can be emulated with different tasks but require a lot more work. I think that PR is the first step, maybe we can go further if necessary.
