Feature request: click to set Gaussian µ in `AdaptGauss()`

[taprs]

Dear Mthrun,

Thanks for the package! The world needs a good interactive GMM fitting app.

It would greatly speed up model fitting if one could set Gaussian parameters (mu and lambda?) by just clicking to the plot area where the curve should be. Should be very straightforward for mu 😄

Cheers,
Nikita
