Sciunit package to containerize the collaborative hydrologic modeling from three Jupyter Notebook(getdata, analysis, and outputviz) as an example of SUMMA

This is an example of how to create sciunit package from Jupyter Notebooks. For this example, I divided a well organized Jupyer Notebook to general three steps such as 1) get data, 2) analysis, 3) output visualization. So I recreated (1) getdata.ipynb, (2) analysis.ipynb, (3) output_viz.ipynb from a well organized Jupyter Notebook.
Then, we can create a sciunit package using \"1_creating_sciunit_package_using_three_step_getdata_analysis_outputviz_jupyter_notebook.ipynb\".
From the previous step, we can create a sciunit package and upload it on HydroShare as a new resource. In addition, we will add \"2_testing_sciunit_repeat_and_visualization.ipynb\" into new HydroShare resource. After that, we open new HydroShare resource, and use \"2_testing_sciunit_repeat_and_visualization.ipynb\" to repeat sciunit package to test reproducibility.
