pystare.expand_intervals() multi_resolution=True doesn't work.

[michaelleerilee]

pystare.expand_intervals(intervals, resolution, multi_resolution=True ) expands all intervals to sids of resolution, not respecting the resolution of the interval.

[michaelleerilee]

Setting the resolution to a non-negative value overrides the multi_resolution flag. The solution is to set the resolution to -1, which tells the function to adapt its output to the resolutions of the input data.

This should be clarified in the documentation.
