double getSemanticCost	(	const EXPERIMENT &	experiment_settings,
		const int	frame_src,
		const int	frame_dst
	)

Function that returns the semantic cost of the transiction from the frame_src to the frame_dst.

The file where the semantic cost will be find is defined in the experiment_settings

Parameters

experiment_settings	- variable with the experiment setting.
frame_src	- first frame of the transition.
frame_dst	- last frame of the transition.

Returns

double - The semantic cost of the transiction of the frame_src to the frame_dst. Returns the complementary value ( 1 - x ).
