Setup a concrete order of the tests, added coverage-html logging in phpunit.xml
Renamed phpunit.xml to phpunit.xml.dist and added phpunit.xml to .gitignore as advised here http://www.testically.org/2010/08/24/best-practice-how-to-ship-phpunit-configuration/
Removed fpdf from .gitignore (should be in vendor folder anyway)
Added report (coverage) and doc (api documentation) folders to .gitignore
Updated copyright in LICENSE
Renamed namespace Gridonic\ESR to more general, library style SwissPaymentSlip\SwissPaymentSlip
Also restructured the whole project folder according to the new namespace
Changed all "inpayment" to "payment" for shorter names
