Challenge Modal 06

This modal displays a list of users and some information about each one. In its current implementation, performance is very poor.

Challenge A: Fix typing lag

Typing into the search input is very sluggish. Refactor this modal so we can type into the search input without any lag.

Challenge B: Fix delay on selecting row

Clicking/selecting each row is noticeably delayed. Refactor this modal so that we can select a row without any delay.
