Changed Document.php to provide more accurate functionality concerning dependencies. And added skeleton for unit test
fleshed out DocumentTest, still incomplete though
- changed regex that filters urls of included files to only accept js and css files
- provided unit test with simple fixture for Base\Www\Html\Document
added parameter to control file extensions to check for in getExternalDependencies
Merge pull request #38 from cflack/master

getExternalDependencies used in includesComplete test limited to js and css files
