    @brief Factory method that creates Process instances for specific process definitions.

    In order to control a process, you need an instance of Process controlling a process
    based on a process description.

    Given a valid process definition, create_process_for will create an appropriate
    instance of Process for you.

    Note that multiple calls to create_process_for with the same process definition
    will create separate instances of Process for this definition.

    This file is a public header, that is, one that a user of libprocess is
    expected to see and use.
    @param pd ProcessDefinition to use for the process object
    @param user optional parameter if using this library in an application; Required if running as a service. if specified will try to run the process under that user.
    Note that this (at least if using windows) only works if that specific user is logged in.

    @note In case function is invoked by multipe threads they must be serialized.
