*
*
* 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);
