	/// Builds a hierarchy of clusters of data containing cluster labels
	let generate<'T> (distance:Distance<float[]>) (linker:Linker.LancWilliamsLinker) (data:array<float[]>) =
	//#region Distance Caching
	let cachedDist = DistanceCaching<float[]> (distance,linker)
	let input = initPairsNR cachedDist data
	whileLoop cachedDist input data.Length

while generate<'T> uses a generic, the data argument is hard coded to array<float[]>, which was not the case in older versions.
