/**
 Test the layout spec or records a snapshot if recordMode is YES.
 @param layoutSpec The layout spec under test or to snapshot
 @param sizeRange The size range used to calculate layout of the given layout spec.
 @param subnodes An array of ASDisplayNodes used within the layout spec.
 @param identifier An optional identifier, used to identify this snapshot test.
 
 @discussion In order to make the layout spec visible, it is embeded to a ASDisplayNode host.
 Any subnodes used within the layout spec must be provided.
 They will be added to the host in the same order as the array.
