/**
 * Class Sides is a printing attribute class, an enumeration, that specifies
 * how print-stream pages are to be imposed upon the sides of an instance of a
 * selected medium, i.e., an impression.
 * <P>
 * The effect of a Sides attribute on a multidoc print job (a job with multiple
 * documents) depends on whether all the docs have the same sides values
 * specified or whether different docs have different sides values specified,
 * and on the (perhaps defaulted) value of the {@link MultipleDocumentHandling
 * MultipleDocumentHandling} attribute.
 * <UL>
 * <LI>
 * If all the docs have the same sides value <I>n</I> specified, then any value
 * of {@link MultipleDocumentHandling MultipleDocumentHandling} makes sense,
 * and the printer's processing depends on the {@link MultipleDocumentHandling
 * MultipleDocumentHandling} value:
 * <UL>
 * <LI>
 * SINGLE_DOCUMENT -- All the input docs will be combined together into one
 * output document. Each media sheet will consist of <I>n</I> impressions from
 * the output document.
 * <P>
 * <LI>
 * SINGLE_DOCUMENT_NEW_SHEET -- All the input docs will be combined together
 * into one output document. Each media sheet will consist of <I>n</I>
 * impressions from the output document. However, the first impression of each
 * input doc will always start on a new media sheet; this means the last media
 * sheet of an input doc may have only one impression on it.
 * <P>
 * <LI>
 * SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- The input docs will remain separate.
 * Each media sheet will consist of <I>n</I> impressions from the input doc.
 * Since the input docs are separate, the first impression of each input doc
 * will always start on a new media sheet; this means the last media sheet of
 * an input doc may have only one impression on it.
 * <P>
 * <LI>
 * SEPARATE_DOCUMENTS_COLLATED_COPIES -- The input docs will remain separate.
 * Each media sheet will consist of <I>n</I> impressions from the input doc.
 * Since the input docs are separate, the first impression of each input doc
 * will always start on a new media sheet; this means the last media sheet of
 * an input doc may have only one impression on it.
 * </UL>
 * <P>
 * <UL>
 * <LI>
 * SINGLE_DOCUMENT -- All the input docs will be combined together into one
 * output document. Each media sheet will consist of <I>n<SUB>i</SUB></I>
 * impressions from the output document, where <I>i</I> is the number of the
 * input doc corresponding to that point in the output document. When the next
 * input doc has a different sides value from the previous input doc, the first
 * print-stream page of the next input doc goes at the start of the next media
 * sheet, possibly leaving only one impression on the previous media sheet.
 * <P>
 * <LI>
 * SINGLE_DOCUMENT_NEW_SHEET -- All the input docs will be combined together
 * into one output document. Each media sheet will consist of <I>n</I>
 * impressions from the output document. However, the first impression of each
 * input doc will always start on a new media sheet; this means the last
 * impression of an input doc may have only one impression on it.
 * <P>
 * <LI>
 * SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- The input docs will remain separate.
 * For input doc <I>i,</I> each media sheet will consist of <I>n<SUB>i</SUB></I>
 * impressions from the input doc. Since the input docs are separate, the first
 * impression of each input doc will always start on a new media sheet; this
 * means the last media sheet of an input doc may have only one impression on
 * it.
 * <P>
 * <LI>
 * SEPARATE_DOCUMENTS_COLLATED_COPIES -- The input docs will remain separate.
 * For input doc <I>i,</I> each media sheet will consist of <I>n<SUB>i</SUB></I>
 * impressions from the input doc. Since the input docs are separate, the first
 * impression of each input doc will always start on a new media sheet; this
 * means the last media sheet of an input doc may have only one impression on
 * it.
 * </UL>
 * </UL>
 * <P>
 * <B>IPP Compatibility:</B> The category name returned by
 * <CODE>getName()</CODE> is the IPP attribute name.  The enumeration's
 * integer value is the IPP enum value.  The <code>toString()</code> method
 * returns the IPP string representation of the attribute value.
