A general function for asymmetric chromatographic peaks.

1	etg(x, H, t1, tt, k1, kt, lambda1, lambdat, alpha, beta)

`x`	times to evaluate function at
`H`	peak height
`t1`	time of leading edge inflection point
`tt`	time of trailing edge inflection point
`k1`	leading edge parameter
`kt`	trailing edge parameter
`lambda1`	leading edge parameter
`lambdat`	trailing edge parameter
`alpha`	leading edge parameter
`beta`	trailing edge parameter

The function evaluated at times x.
