    Compares list of attributes with active attributes in Active Directory. Currently only works with user and computer class.

.DESCRIPTION
    Compares list of attributes with active attributes in Active Directory.
    This function is used to spot unusal attributes.
    
    Example where an attribute is found in AD and not in compare list:
    InputObject                   SideIndicator                                              
    -----------                   -------------                                              
    TopSecretAttribute            =>
