Lab js

[Yury-Shevchenko]

Dear Teon, here is the update that we can use for the next PD.

• The four lab.js tasks are running, collecting and displaying the data
• UI is changed according to the comments on Notion Teon, could you make a release? After updating my OS to Catalina, I got into problems with building a dmg file.

thanks @Yury-Shevchenko. I managed to get the build working again for the Mac. there was a problem with the memory allocation for node. I upped the limit to 4gb based on https://stackoverflow.com/questions/26094420/fatal-error-call-and-retry-last-allocation-failed-process-out-of-memory/48895989#48895989 closing this PR as I have merged all your changes to master. feel free to delete your branch and update your master branch to be in sync with main repo. will need to tackle the windows build problem next
