[Dip] Restricted Master Solution Value

[Kipp Martin]

Hi Matt:

Thanks for this information. Very useful.

What is strange is that

DecompAlgo * algo          = getDecompAlgo();

compiles and executes just fine without

   #include "DecompAlgo.h"

I will reveal my utter lack of C++ here, but I just assumed that since 
the above worked without

#include "DecompAlgo.h"

that the DecompAlgo.h was getting included somewhere earlier in the food 
chain like in

#include "OSDipApp.h"

and did not even bother to look for DecompAlgo.h. Since DecompAlgo.h 
was not getting included I have no idea why

DecompAlgo * algo          = getDecompAlgo();

would compile since it seems like algo would be an unknown data type. 
This strikes me as odd, but anyway at least it works now.

Thanks
