Panel_Fichas tab control: Deploys and handle HTML Tab Control using pure PHP

This class generates an HTML table that acts like the Tab Control we use in GUIs. It has a tab bar in first top row with the appropiate links and names of every tab is defined. The second row of the table deploys the contents of the active tab, which can turn out to be a string contained in a variable, a PHP constant o a file (which will be included right in place).

The class provides functions to add a tab, remove a tab, and set or get the active tab.

The class outputs the navigation bar as pure HTML code. NO layers or dynamic HTML is used, and the active tab is reloaded dynamically from PHP each time a link in the bar is pressed.

The presentation styles of the active and inactive tabs are customizable.

The code and comments of the class are in Spanish.

Hope you enjoy it!
