Embodiment Construction

[0048] In the present application, it should be understood that the terms "comprising", "having", "including" and the like specify the presence of stated features, quantities, steps, operations, elements, parts or combinations thereof, but do not exclude the presence or addition of an or multiple other features, quantities, steps, operations, elements, parts or combinations thereof.

[0049] Also, the same reference numerals will be used throughout the drawings to designate components performing similar functions or operations. In the case where it is described in the specification that one component is connected to another component, not only one component may be directly connected to another component, but one component may be indirectly connected to another component via another component. Furthermore, the inclusion of certain elements does not mean the exclusion of other elements, but means that these elements may be additionally included unless otherwise stated.
