Effect groups - grouping techniques in DirectX 11 Effects

See http://msdn.microsoft.com/en-us/library/windows/desktop/ff476120.aspx for details, but in general, in .fx:

fxgroup Group1
{
     technique11 Tech1 { ... }
     technique11 Tech2 { ... }
}

and in C++:

pEffect->GetTechniqueByName( "Group1|Tech2" );

or

pEffect->GetGroupByName("Group1")->GetTechniqueByName( "Tech1" );
