Add API ref docblocks for subj.

PHP SDK API described in the single file (PHP stub), which is used by phpDocumentor project to generate nice HTML documentation

https://github.com/couchbase/php-couchbase/blob/master/api/couchbase.php#L92

The task is to add php doc comments to the classes and methods.

To verify output the following steps might be used:

curl -L -o/tmp/phpdoc.phar curl https://github.com/phpDocumentor/phpDocumentor/releases/download/v3.0.0-rc/phpDocumentor.phar

php  /tmp/phpdoc.phar -t /tmp/output -d api/

where api/ is a directory inside the PHP SDK source tree

After that, the docs will be available with the browser at file:///tmp/output/index.html
