DETAILED DESCRIPTION OF THE INVENTION

In the Summary of the Invention above, and in the Detailed Description of the Invention, and in the accompanying drawings, reference is made to particular features (including method steps) of the invention. It is to be understood that the disclosure of the invention in this specification includes all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a particular aspect, a particular embodiment, or a particular Figure, that feature can also be used, to the extent appropriate, in the context of other particular aspects, embodiments, and Figures, and in the invention generally.

The term “comprises” and grammatical equivalents thereof are used herein to mean that other elements (i.e. components, ingredients, steps etc.) are optionally present. For example, a pedestal “comprising” (or “which comprises”) components A, B and C can contain only components A, B and C, or can contain not only components A, B and C but also one or more other components. The term “at least” followed by a number is used herein to denote the start of a range beginning with that number (which may be a range having an upper limit or no upper limit, depending on the variable being defined). For example “at least 1” means 1 or more than 1. The term “at most” followed by a number is used herein to denote the end of a range ending with that number (which may be a range having 1 or 0 as its lower limit, or a range having no lower limit, depending upon the variable being defined). For example, “at most 4” means 4 or less than 4. When, in this specification, a range is given as “(a first number) to (a second number)” or “(a first number)−(a second number)”, this means a range whose lower limit is the first number and whose upper limit is the second number. For example, “from 8 to 20 inches” or “8-20 inches” means a range whose lower limit is 8 inches, and whose upper limit is 20 inches. The terms “plural” and “plurality” are used herein to denote two or more than two items.

Where reference is made herein to “first” and “second” elements, this is generally done for identification purposes; unless the context requires otherwise, the first and second elements can be the same or different, and reference to a first element does not mean that a second element is necessarily present (though it may be present). Where reference is made herein to “a” or “an” element, this includes the possibility that there are two or more such elements (except where the context excludes that possibility). Where reference is made herein to two or more elements, this includes the possibility that the two or more elements are replaced by a lesser number or greater number of elements providing the same function (except where the context excludes that possibility). The numbers given herein should be construed with the latitude appropriate to their context and expression; for example, each number is subject to variation which depends on the accuracy with which it can be measured by methods conventionally used by those skilled in the art.

Some of the components used in this invention are defined as having “a substantially constant generally rectangular core cross-section”. Those components are also defined as having recessed and projecting sections and/or channels in their top and/or bottom surfaces. The term “core cross-section” is used herein to denote the largest-area cross-section which can be drawn by four straight lines within the actual cross-section of the component. The term “generally rectangular core cross-section” is used herein to denote any core cross-section which has a closed perimeter and which is rectangular or which provides the same functionality as a rectangular cross-section. Thus, the generally rectangular core cross-section can, for example, be a square; a rectangle whose height is substantially greater than, e.g. at least twice, its width; a rectangle whose height is substantially less than, e.g. less than 0.5 times, its width; a parallelogram; a trapezium; or a circle or an oval which has been modified so that the cross-section has flat top and bottom surfaces. The component can be solid, or it can contain one or more voids. The term “substantially constant” in the term “substantially constant generally rectangular core cross-section” means that the cross-section is constant, as is generally preferred, or varies (regularly or irregularly) in a way which provides the same functionality, and optionally the same appearance, as a constant cross section.
