Tips for development of a new block

[ml-evs]

There are a few steps that need to be undertaken to create a new block as of datalab 0.4, as we discussed. To summarise, I would say the best option is to copy the EIS block, both Python and JS code.

• Copy the eis folder in from apps into the desired block name
• The block can save keys under self.data: bokeh_plot_data will cause a bockeh plot to be shown in the UI, freeform_comment will render an HTML comment.
• Add a link to the block in the blocks/__init__.py file where other blocks are registered

Then in the UI:

• Copy the webapp/src/components/datablock/EISBlock.vue into the desired new file
• Register the new component in resources.js with the desired names

In the UI in the copied .vue file the accepted extensions need to also be edited
