/***************************************************************
* Function: void radioButtons_CheckedChanged()
*
* Use: This method checks which radio button was selected by the

* Depending on the selection, a specific task is done,
* whether it be create a new entry, search for a person, office or
* phone number. Our data is changed and output differs
* depending on which radio button is selected.
*
* Parameters: 2 parameters - object sender, EventArgs e
*
* Returns: Nothing
*
* Notes: We use a series of condition statements to check which
* radio button is selected. After a radio button is selected, the
* button is cleared so the user can choose to complete another
* task, or quit the form.
