initial implementation of the linregress
better way to filter out None using np.not_equal
fixing typos in test names
register the linregress function
prune trailing whitespace
make linear regression available from the java script interface
fix missing comma
add numpy and scipy to the RPM requirements
the calender in the composer can now be used to select dates in the future for prediction
optimized linregress to return a minimal timeseries whith two datapoints
