2* vkBeautify - javascript plugin to pretty-print or minify text in XML, JSON, CSS and SQL formats.
3*
4* Version - 0.99.00.beta
5* Copyright (c) 2012 Vadim Kiryukhin

12*
13* Pretty print
14*
15* vkbeautify.xml(text [,indent_pattern]);
16* vkbeautify.json(text [,indent_pattern]);
17* vkbeautify.css(text [,indent_pattern]);
18* vkbeautify.sql(text [,indent_pattern]);
19*
20* @text - String; text to beatufy;
21* @indent_pattern - Integer | String;
22* Integer: number of white spaces;
23* String: character string to visualize indentation ( can also be a set of white spaces )
24* Minify
25*
26* vkbeautify.xmlmin(text [,preserve_comments]);
27* vkbeautify.jsonmin(text);
28* vkbeautify.cssmin(text [,preserve_comments]);
29* vkbeautify.sqlmin(text);
30*
31* @text - String; text to minify;
32* @preserve_comments - Bool; [optional];
33* Set this flag to true to prevent removing comments from @text ( minxml and mincss functions only. )
34*
35* Examples:
36* vkbeautify.xml(text); // pretty print XML
37* vkbeautify.json(text, 4 ); // pretty print JSON
38* vkbeautify.css(text, '. . . .'); // pretty print CSS
39* vkbeautify.sql(text, '----'); // pretty print SQL
40*
41* vkbeautify.xmlmin(text, true);// minify XML, preserve comments
42* vkbeautify.jsonmin(text);// minify JSON
43* vkbeautify.cssmin(text);// minify CSS, remove comments ( default )
44* vkbeautify.sqlmin(text);// minify SQL
