clean up: whitespaces, added PHPDocs, new lines
MOB-1138: created lyrics.setup.php file with all require_once() instructions
small whitespaces changes and added first tests for ArtistScraper.class.php
added trimming in parsed album data, changed "Album" array key to "album" so it is consistant in the code
added tests for ArtistScraper::getAlbumData()
removed unused variable
changed uppercases to lowercases
added @desc annotation in the PHPDocs
made BaseScraper::getTemplateValues() public method for testing reasons but also since it is a getter - why to make a getter not public?
first tests for main method BaseScraper::getTemplateValues
added failing use case for BaseScraper::getTemplateValues()
fixed the code failing in unit tests
added test for ArtistScraper::getAlbumPic() and checked how the file name is generated
