Editing WoW:API Frame GetAttribute

{{widgetmethod}}
Returns the value of a specific attribute (or an attribute matching the prefix/suffix arguments).
 value = frame:GetAttribute(name);
 value = frame:GetAttribute(prefix, name, suffix);

==Arguments==
; prefix : String - modifier prefix string: a concatenation of alt-, ctrl-, and shift-, whichever apply, in that order.
; name : Attribute name. If passed as the only argument, this may be a fully qualified value; otherwise, it is the unmodified name of the attribute being retrieved.
; suffix : String - button suffix string: either a numeric string or a dash followed by an arbitrary button name.

== Returns ==
; value : Mixed - the value of the matching attribute; nil if no attribute matched the arguments.

== Matching order ==
When invoked with three arguments, this function attempts to return attributes in the following order (returning the first attribute that exists):
# prefix .. name .. suffix 
# "*" .. name .. suffix
# prefix .. name .. "*" 
# "*" .. name .. "*" 
# name
