description of an embodiment with several components in communication with each other does not imply that all such components are required to the contrary a variety of optional components may be described to illustrate a wide variety of possible embodiments of one or more of the inventions and in order to more fully illustrate one or more aspects of the inventions similarly although process steps method steps algorithms or the like may be described in a sequential order such processes methods and algorithms may generally be configured to work in alternate orders unless specifically stated to the contrary in other words any sequence or order of steps that may be described in this patent application does not in and of itself indicate a requirement that the steps be performed in that order the steps of described processes may be performed in any order practical further some steps may be performed simultaneously despite being described or implied as occurring non simultaneously e g because one step is described after the other step moreover the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto does not imply that the illustrated process or any of its steps are necessary to one or more of the invention s and does not imply that the illustrated process is preferred also steps are generally described once per embodiment but this does not mean they.
