Static version of the library and other things?

[beppe9000]

I think it could be cool to be able to do oneliners like this, with static methods:

if (\Dorantor\FileLock::acquire('path')){

  //do work...

\Dorantor\FileLock::release('path');
}

Also fluent locking with closures:

\Dorantor\FileLock::lock('/path/file')->acquired(function(){echo("HELLO FROM LOCK!");});

\Dorantor\FileLock::lock('/path/file')->failure(function(){echo("LOCK NOT ACQUIRED!");});

\Dorantor\FileLock::lock('/path/file')->acquired(function(){echo("HELLO FROM LOCK!");})->failure(function(){echo("LOCK NOT ACQUIRED!");});
