First draft of new analysis tab

[joasand]

This update contains a new layout of the landing page of the "Analyse" tab. The contents of the value boxes have not been completely finalized, and the plots can be developed further. A network diagram to analyze peers is also on the shortlist. But before proceeding with these improvements, it would be useful to have a discussion regarding the code changes in this pull request

We'll implement the following changes:

• [ ] Bootstrap tab is removed and integrated with the Analyse tab
• [ ] Bootstrap options are build into the Analyse options
• [ ] New checkbox to select if bootstrap should be performed or not (default value FALSE). The button must be disabled when RTS is not CRS or VRS
• [ ] Export file will automatically add bootstrapped results if box is checked
• [ ] Table options should be conditioned on which table is shown in the UI
• [ ] Use a tab design with the Analyse tab with the following tabs: "Summary", "Efficiency scores" (this will include bootstrapped values), "Peers", "Scale efficiency"
• [ ] Add caching to bootstrap function to increase performance

This PR has gone stale because of the changes to the underlying code we are preparing for the 0.4.0. I suggest that we create a new branch based off the 0.4.0 code when it's released and recreate this PR with the new codebase. This PR can be closed and the branch removed later on.
