/**
 * Abstract utility class for parsing binary files.

 * Provides a library of methods to quickly navigate and extract various data

 *
 * File access is managed via a {@link Zend_Pdf_FileParserDataSource} object.
 * This allows the same parser code to work with many different data sources:
 * in-memory objects, filesystem files, etc.
