[EEG Browser] Signal Visualization, Events, Electrode map and EEG split files support

[laemtl]

This PR adds dynamic visualization of EEG based on a previous project started by Armin Taheri (https://github.com/aces/react-series-data-viewer).
These changes and include cleanup of older code in the Electrophysiology Browser and new features like viewing the list of Events, and an Electrode Map dynamically plotted from the BIDS-compliant coordinates file.

The visualization component uses svg (Visx|D3) and introduces a new stack of dependencies:

Ramda (https://ramdajs.com)

A practical functional library for JavaScript programmers.

Redux (https://redux.js.org)

A Predictable State Container for JS Apps

Visx (https://airbnb.io/visx)

A collection of expressive, low-level visualization primitives for React.

RxJS (https://rxjs-dev.firebaseapp.com/guide/overview)

RxJS is a library for composing asynchronous and event-based programs by using observable sequences.
It provides one core type, the Observable, satellite types (Observer, Schedulers, Subjects) and operators to allow handling asynchronous events as collections.

TypeScript (https://www.typescriptlang.org)

A static type checker for javascript.

Preview

To test

• install protoc:
  • sudo apt-get install -y protobuf-compiler (Ubuntu > 16.10)
  • brew install protobuf (Mac)
  • https://github.com/protocolbuffers/protobuf/blob/master/src/README.md
• run npm install
• The MRI pipeline must be run on raisinbread to get the signal chunks
• To view all the functionalities, an event and electrode file is needed in the BIDS package.

To discuss

This PR contains the protobuf file used to generate the frontend (js) and backend (python, used in Loris MRI) chunk message encoder/parser. I'm not sure this file should be stored here and what would be a good compilation pipeline.

To fix

The electrode map needs to support a coordinate system to perform appropriate rotations.

@cmadjar, @driusan Fixed.

@maltheism Do you have time to review?

@laemtl one quick question I thought of while I'm now testing this PR. You have protobuf support for macOS and ubuntu. I'm just wondering if centos that LORIS supports would also have something for protobuf?

[maltheism]

@laemtl when visiting http://localhost/electrophysiology_browser/ I get the following in browser console:
Warning: Failed prop type: Invalid prop value supplied to SelectElement.

Warning: Failed prop type: Invalid prop value of type boolean supplied to TextboxElement, expected string.

Good point but unrelated to my changes in this PR. I suggest to open an issue to address those errors in all modules.

Yes, for CentOS users can use the third link:

install protoc:

sudo apt-get install -y protobuf-compiler (Ubuntu > 16.10)
brew install protobuf (Mac)

Hi @laemtl, thanks for the answers and you're right I didn't realize you weren't using those components while the warnings are coming from the core filter/table. It's taking me some additional time to setup the MRI pipeline and so far I can only visit /electrophysiology_browser for testing.

[maltheism]

I'm approving the javascript part of the PR. This PR is large considering all of the work done. Other things will be necessary like handling rare errors but that can be done in separate PRs after this PR is merged.

@cmadjar ready for your manual tests. :)

@driusan - ready for your review -- this has 2 approvals and is needed for the release. thanks!
