Interactive widgets supporting nix on jupyter notebook

[hkchekc]

This PR provides basic function of interacting with visualized nix data on jupyter notebook:

• Checkbox for en/dis-able the dataarrays plotted
• Marking the tagged area by Tags with a drop-down menu
• Provide an basic example of how to use the widget
• Support the matplotlib interactive functions (zooming ...) in the notebook

Also, added some init files.

@jgrewe Maybe do you have any suggestions on what functions can be added?

[achilleas-k]

It's nice to have an example, but if the file isn't in the repository, or available somewhere, it's not very useful. Could use one of the files in https://gin.g-node.org/G-Node/nix-examples/ the same way it was recently added to an example script by @jgrewe in the NIX repo: https://github.com/G-Node/nix/blob/4565c2d7b363f27cac88932b35c085ee8fe975a1/docs/code/relacs_example.py#L105-L122

[achilleas-k]

Nice work. I loaded the relacs example and played around with it a bit. A few bugs here and there, but good POC.

There's a bug when plotting data arrays with set dimensions. I think fix that before we merge and then we can continue with more features and enhancements for followup PRs.

@hkchekc I am actually not the Jupyter notebook guy and had to setup my computer after HDD breakdown today. Will have a closer look tomorrow. Wanted to bring up the examples in the nix docs (as @achilleas-k pointed out earlier).

[jgrewe]

in addition to the bug @achilleas-k pointed at, I think I would appreciate the following two points:

• implement the loading of the data if it is not present in the current directory
• add something like an overview of the data that is available for plotting:

  type:                             
  nix.timeseries.regular:     10
  ...

  perhaps to also show how one can find the respective arrays of a given type.

[hkchekc]

@jgrewe I think I will add those in the next PR. But I don't really understand the first point, Do you mean to move the nix file to the current directory when it is interacted with?

Also I want to ask if you have some example data files for not only Line and Events plotter, but also Images and bar charts.

@hkchekc the file download is what I meant :) we do have the test file for nixview (https://github.com/bendalab/NixView/blob/master/test/nix_test.h5) that contains image data.
