add fit_double_gaussian

fits atom and it’s mirror image to a 1d double gaussian
edited fit_double_gaussian and cloud_distribution

added a function in cloud_distribution called fit_double_gaussian. One
can call it and pass a file to it to get a picture of the fit. Haven’t
tested it yet. Also commented out some lines used for testing in
fit_double_gaussian.py.
fixed fitting bug

guesses for hwhm was wrong, resulting some data sets not fitting
properly. Now changed it to be half of the distance between the two
peaks.
fitting is semi-working

fitting double gaussian is working, some times it fails (maybe 96% of
the time). scipy.signal.find_peak_cwt does not see the right peaks
sometimes. added new dictionary "d_peaks" to cloud_distribution for
distances between two clouds
add more dists

added more dictionaries to keep track of double gaussian fit parameters.
sigma_1 and sigma_2 are not necessarily pointing to the correct peaks
now. need to fix that.
