//USAGE INSTRUCTION. displaycontact(1st paramter, "2nd paramter", "3rd paramter", "4th paramter")
//1st parameter: Input the name of the array containing the list of email addresses. To display one single email, input the corresponding array element. 
//2nd parameter: Input the CSS Classname that is to be applied. Enter arbitrary name for none.
//3rd parameter: Input either "form" or "text." Former will display email in drop down menu. Later in plain text. Only "text" mode supports displaying of single email address!
