/*
This function places focus on the first field of the page and
sets the tabIndex on the input fields of the firs form on the page.

It is used to create the following tabbing order: all fields, Next, Back, Delete This Registration.

It works as following: All visible input elements on a page are assigned the tabIndex in the order they are created. 
The buttons in the footer are set to positive tabIndex manually (9999,9998 etc.). 
We want to force a tab from the last form field to the "Next" btn. Once we set the form elements 
tabindex to positive number, the browser proceeds with the positive tabIndex instead of 0 tabIndex.
