Added features from @uuf6429's PR:
- Allow parsing from strings (instead of Reflector object only)
- Get method can be forced to return array of tags (common usage for param/property/method tags)
- Get method default result value can be changed (helpful when you want to iterate on result)
- Allows parsing of single-line docblocks
- Various minor code fixes; removed unused variables, standardized code style etc.
- Added php-cs-fixer dev dependency
