 *
 * Synopsis:
 * ----------
 *
 * This class provides the following functionality:
 *    1. Parse BibTex into a logical data javascript data structure.
 *    2. Output parsed BibTex entries as HTML, RTF, or BibTex.
 *
 *  
 * The following usage instructions have been copyed and adapted from the PHP instructions located
 * at http://pear.php.net/manual/en/package.structures.structures-bibtex.intro.php
 * Introduction
 * --------------
 * Overview
 * ----------
 * This package provides methods to access information stored in a BibTex
 * file. During parsing it is possible to let the data be validated. In
 * addition. the creation of BibTex Strings as well as RTF Strings is also
 * supported. A few examples
 * 
 * Example 1. Loading a BibTex File and printing the parsed array
 * <script src="BibTex.js"></script>
 * <script>
 * bibtex = new BibTex();
 * bibtex.content = content; // the bibtex content as a string
 * 
 * bibtex->parse();
 * alert(print_r($bibtex->data,true));
 * </script>
 * 
 * 
 * Options
 * --------
 * Options can be set either in the constructor or with the method
 * setOption(). When setting in the constructor the options are given in an
 * associative array. The options are:
 * 
 * 	-	stripDelimiter (default: true) Stripping the delimiter surrounding the entries. 
 * 	-	validate (default: true) Validation while parsing. 
 * 	-	unwrap (default: false) Unwrapping entries while parsing. 
 * 	-	wordWrapWidth (default: false) If set to a number higher one
 * 	    that the entries are wrapped after that amount of characters. 
 * 	-	wordWrapBreak (default: \n) String used to break the line (attached to the line). 
 * 	-	wordWrapCut (default: 0) If set to zero the line will we
 * 	    wrapped at the next possible space, if set to one the line will be
 * 	    wrapped exactly after the given amount of characters. 
 * 	-	removeCurlyBraces (default: false) If set to true Curly Braces will be removed. 
 * 
 * Example of setting options in the constructor:
 * 
 * Example 2. Setting options in the constructor
 * bibtex = new BibTex({'validate':false, 'unwrap':true});
 * 
 * 
 * Example of setting options using the method setOption():
 * 
 * Example 62-3. Setting options using setOption
 * bibtex = new BibTex();
 * bibtex.setOption('validate', false);
 * bibtex.setOption('unwrap', true);
 * 
 * Stored Data
 * ------------
 * The data is stored in the class variable data. This is a a list where
 * each entry is a hash table representing one bibtex-entry. The keys of
 * the hash table correspond to the keys used in bibtex and the values are
 * the corresponding values. Some of these keys are:
 * 
 * 	-	cite - The key used in a LaTeX source to do the citing. 
 * 	-	entryType - The type of the entry, like techreport, book and so on. 
 * 	-	author - One or more authors of the entry. This entry is also a
 * 	    list with hash tables representing the authors as entries. The
 * 	    author has table is explained later. 
 * 	-	title - Title of the entry. 
 * 
 * Author
 * ------
 * As described before the authors are stored in a list. Every entry
 * representing one author as a has table. The hash table consits of four
 * keys: first, von, last and jr. The keys are explained in the following
 * list:
 * 
 * 	-	first - The first name of the author. 
 * 	-	von - Some names have a 'von' part in their name. This is usually a sign of nobleness. 
 * 	-	last - The last name of the author. 
 * 	-	jr - Sometimes a author is the son of his father and has the
 * 	    same name, then the value would be jr. The same is true for the
 * 	    value sen but vice versa. 
 * 
 * Adding an entry
 * ----------------
 * To add an entry simply create a hash table with the needed keys and
 * values and call the method addEntry().
 * Example 4. Adding an entry
 * bibtex                         = new BibTex();
 * var addarray                   = {};
 * addarray['entryType']          = 'Article';
 * addarray['cite']               = 'art2';
 * addarray['title']              = 'Titel of the Article';
 * addarray['author'] = [];
 * addarray['author'][0]['first'] = 'John';
 * addarray['author'][0]['last']  = 'Doe';
 * addarray['author'][1]['first'] = 'Jane';
 * addarray['author'][1]['last']  = 'Doe';
 * bibtex.addEntry(addarray);

 * <code>
 * bibtex = new BibTex();
 * bibtex.content = '....';
 *
 * bibtex.parse();
 * print "There are "+bibtex.amount()+" entries";

 * bibtex.content="...";
 * bibtex.parse();
 * for (var i in bibtex.data) {
 *  alert( bibtex.data[i]['title']+"<br />");

 * Example 3: Adding an entry and printing it in BibTex Format
 * <code>
