    Quantum Contact Manipulator is a dedicated set of code
    for managing the dhtml of QuantumRadiology's contact page. 
    It is designed to make use of "blocks" or divs that contain
    a link and a div which will be triggered on and off.
    
    Each div should have base "ID" which should be registered in
    arr_ContactBlocks below. Additionally, each link should be 
    labeled by the ID plus a distinct appendage which can also be
    set below. The default appendage for a link is "Link"...
    
    e.g.
    If the block's id is "Identifier" then the link to control
    the block will be called "IdentifierLink". 
    
    This same convention goes for the inner div which will be 
    opened and closed. These two values can be altered by changing
    str_LinkAppendage and str_DataAppendage below.
    
    While the data div is opened and closed, the link's class will
    be toggled as well. The two variables, str_ClosedStateLinkClass
    and str_OpenedStateLinkClass can be set to different classes
    if you so desire.
    
    ** The Main Container div is not necessary.
