CostDBEntryStatsRF::CostDBEntryStatsRF	(	const CostDBEntryStatsRF &	stats1,

Constructor.

Combines two statistics into one using coefficient as a weighting factor on interpolating the statistics. For example, if weighting factor is 0.4, the first area 100 and the second 200, area of new statistics will be 140. delay and energy will be handled similarly.

Parameters

stats1	First statistics.
stats2	Second statistics.
coefficient	Weighting factor.
