Summary

Clean up inst and migrate to new data filter mod. close #515 and #506.

Test notes

Just make sure the app is still running as expected, with a special focus on the data filter functionality.

Just went through everything. I'm not able to get the Hepatic Safety Explorer to load. I'm not sure if this is just an issue with my environment or not.

Everything else looked good to me though. I tested the filtering on every chart and they all looked to take that into account.

Thanks @elimillera. Will merge this up in the morning.

Were there any errors in the R console or in the javascript console in the web browser (hit ctrl-shift-j in chrome to open)related to hep-explorer? If there's nothing obvious, I might ask you to re-create bug this on our next Friday call so that we can take a look together and see if we can figure out what is going on.

Going to go ahead and merge here, since there were no changes to hep-explorer. Will work on sorting out the bug in a separate issue/PR.
