Add a small object-oriented wrapper around DDetours

[GoogleCodeExporter]

DelphiDetours is a great library!  I've been using it very happily.

One thing I thought of is that you could use it in an object-oriented way: to 
install a hook/detour object, and remove the hook by freeing the object.  
(Currently it's used only procedurally.)  So, for example:

TMyProc = function(A : Integer): Boolean; // Use this to type-safely declare 
the prototype of the method you're detouring
...
FDetour : TDetour<TMyProc>; // Using generics, now it's a detour only for this 
type of method
...
FDetour := TDetour<TMyProc>.Create(@Original, @Replacement); // Installs the 
detour
FDetour.Free; // Uninstalls the detour

Meanwhile, while it's installed, you can call the trampolined function like so:
FDetour.Trampoline(5); // Calls the trampoline / original

It's just a neat OO style of using the detour, and I think suits Delphi quite 
well.

In fact I wrote a small wrapper unit that does exactly the above, and so if you 
like it you are very welcome to add it to DDetours! I've attached it here.

Great idea , thanks  David.

Do you agree that i merge DDetoursOO.pas unit into a single unit with the 
DDetours.pas unit ?

Sure, feel free.  Would you mind crediting me as the author of the class though?
