// LSQ line fitting to the a number of samples.
// The trendline is the leading point in the fit;
// the bands are calculated somewhat differently, check the math below and adapt to
// your own needs as appropriate
// also the point estimate is given by the geometric mean
// MathPow(HCCC,.025) (see function "get_avg" below) rather than
// more standard estimates.
// It's computationally fairly intensive
