* Pretty print
*
* vkbeautify.xml(text [,indent_pattern]);
* vkbeautify.json(text [,indent_pattern]);
* vkbeautify.css(text [,indent_pattern]);
* vkbeautify.sql(text [,indent_pattern]);
*
* @text - String; text to beatufy;
* @indent_pattern - Integer | String;
* Integer: number of white spaces;
* String: character string to visualize indentation ( can also be a set of white spaces )
* Minify
*
* vkbeautify.xmlmin(text [,preserve_comments]);
* vkbeautify.jsonmin(text);
* vkbeautify.cssmin(text [,preserve_comments]);
* vkbeautify.sqlmin(text);
*
* @text - String; text to minify;
* @preserve_comments - Bool; [optional];
* Set this flag to true to prevent removing comments from @text ( minxml and mincss functions only. )
*
* Examples:
* vkbeautify.xml(text); // pretty print XML
* vkbeautify.json(text, 4 ); // pretty print JSON
* vkbeautify.css(text, '. . . .'); // pretty print CSS
* vkbeautify.sql(text, '----'); // pretty print SQL
*
* vkbeautify.xmlmin(text, true);// minify XML, preserve comments
* vkbeautify.jsonmin(text);// minify JSON
* vkbeautify.cssmin(text);// minify CSS, remove comments ( default )
* vkbeautify.sqlmin(text);// minify SQL
*
