moved code-coverage to scrutinizer
updated coverage icon of README file
improved internal method EnumMap::initEnum()
PHPDoc: fixed possible enum values descriped as 'scalar' by 'null|boolean|int|float|string'
PHPDoc: @return static
Enum::get() An instance of the called class will return an enum of the same value of the called class
The static declaration must come after the visibility declaration
added @method annotations for test assets
Run travis tests on PHP-5.6 and HHVM
travis: fast_finish:true and allow_failures: hhvm
replaced internal method Enum[Set|Map]::initEnum() by Enum::get() since this does the same and is a little bit faster
EnumSet: fixed copy-past failures in comments and exception message
Merge branch 'master' of https://github.com/marc-mabe/php-enum into EnumSet_BitSet
