[proposal] Code cleanup and standartise

There is too much noice in code with comments.

They looks like for PEAR but not compatible (checked with phpcs).

As I see this project hosted on composer but not on pear, so my proposal is to use psr2 standard, and remove all that noisy comments, this will make code cleaner.

Also you can run code sniffer on travis to check is code in PRs is compatible with yours, this will allow to maintain code readability and clean all the time.

To install php code sniffer on your system globally you can run: `composer global require "squizlabs/php_codesniffer=x"`

Then you can run: `phpcs --ignore=vendor --standard=psr2 ./` to check code. Or install SublimeLinter-phpcs to do it automatically for you.

Also it will be very nice to have mess detector running but it need more refactoring on current code, will check this later on
