Large size type configuration for the ExternalString.

/*!
 * @class ExternalConfigLarge
 * 
 * @headerfile <seqan/file.h>
 * 
 * @brief Large size type configuration for the @link ExternalString @endlink.
 * 
 * @signature template <[typename TFile[, unsigned SEQAN_PAGESIZE[, unsigned
 *            FRAMES]]> struct ExternalConfigLarge;
 * 
 * @tparam TFile The @link File @endlink type to use. Default:
 *               <tt>File&lt;&gt;</tt>.
 * @tparam SEQAN_PAGESIZE The number of values in one page. This should be a
 *                        power of 2 to speed up transfer and calculations.
 *                        Default: 2<sup>20</sup>.
 * @tparam FRAMES The number of pages that should reside in internal memory. To
 *                enable prefetching and automatic swap-out, <tt>frames</tt>
 *                should be greater than 1. Default: 2.
 * 
 * @section Remarks
 * 
 * When using this configuration ,the <tt>Size</tt> type of the ExternalString
 * is <tt>Size</tt> type of <tt>TFile</tt>. Normally, this is a 64 bit integer.
 * For a smaller size type use ExternalConfig.
 * 
 * Some data structures store size types values (e.g. suffix arrays in indices).
 * To save memory, you should think o fusing ExternalConfig.
