Interpolate along the function described by (keys[length], values[length]) for the passed searchKey.
SearchKeys outside the range keys[0]-keys[Length] clamp to the min or max value. This function assumes the number of pairs (length) will be small and a linear search is used.
Repeated keys are allowed for discontinuous functions (so long as keys is monotonically increasing). If key is the value of a repeated scalar in keys the first one will be used.
