 * our class with it's own template. Class is going to manipulate template and produce nicely
 * formatted output
 *
 * It does not matter in which file and under which tag template is defined, we just specify
 * how the tag can be found. In our case, i have created a file called widgets.html. It would be
 * a file containing few different templates for few different classes. So this file won't be
 * the only one to use that template.
