Trajectory dataframe must have at least two rows

[k1th]

Should this be added? (skipping single point data frames)

In qgisUtils.py

    for key, value in df_by_id.items():
        if len(value) < 2:
            continue
        traj = Trajectory(key, value)
        trajectories.append(traj)

and in splitOnDayBreakAlgorithm.py:

    def split(self, mode='daybreak'):
        result = []
        if mode == 'daybreak':
            dfs = [group[1] for group in self.df.groupby(self.df.index.date)]
            for i, df in enumerate(dfs):
                if len(df) < 2:
                    continue

Yes, it should. Feel free to submit a pull request.

I'm planning to replace most of the current data handling implementation with http://movingpandas.org which is considerably further developed than the current Trajectools code base.
