+*
+*        @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 )

+*        @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
