/**
 * @file   viewer.php
 * @author Collin Haines - Center for Digital Humanities
 *
 * The metaphorical end-game of the Plants and Planters - Henry Ravenel site.  This
 * page allows our users to view two main categories: Transcripts or Specimens. All
 * search results, map details, and random clicks will end here at one point.
 *
 * This page uses URL rewriting through the .htaccess file.
 *
 * NOTE: The terms 'Transcript' and 'Manuscript' are used interchangeably from here
 * on in unless referring to the human-typed version of text within an image.
 *
 * @param string type
 *   Acceptable as either transcript or specimen.
 * @param string institute
 *   Must be Carolina when the type is equal to specimen.  Otherwise,  is fair game
 *   as long as it matches correctly with the manuscript pointer.
 * @param int number
 *   Representing a pointer (transcript) or catalog number (specimen).
 * @param string search
 *   Mainly used when arrving from search results, this'll tell the application any
 *   word(s) to highlight.
