/**
* the wrapper around the PHP_Shell class
*
* PHP Version 5
*
* - load extensions
* - set default error-handler
* - add exec-hooks for the extensions
*
* To keep the namespace clashing between shell and your program
* as small as possible all public variables and functions from
* the shell are prefixed with __shell:
*
* - $__shell is the object of the shell
* can be read, this is the shell object itself, don't touch it
* - $__shell_retval is the return value of the eval() before
* it is printed
* can't be read, but overwrites existing vars with this name
* - $__shell_exception is the catched Exception on Warnings, Notices, ..
* can't be read, but overwrites existing vars with this name
