/**
 * The ezcArchiveCentralDirectoryHeader class represents the Zip central directory header.
 *
 * ezcArchiveCentralDirectoryHeader can read the header from an ezcArchiveCharacterFile or ezcArchiveEntry.
 *
 * The values from the headers are directly accessible via the class properties, and allows
 * reading and writing to specific header values.
 *
 * The entire header can be appended to an ezcArchiveCharacterFile again or written to an ezcArchiveFileStructure.
 * Information may get lost, though.
 *
 * The central directory format[1]:
 *
 * <pre>
 *  [file header 1]
 *  .
 *  .
 *  .
 *  [file header n]
 *  [digital signature] <-- Optional, TODO: check if implemented.
 * </pre>
 *
 * The Central Directory Header has the following structure:
 *
 * <pre>
