Revert "added columns plugin"

This reverts commit 4960e1b54c7ad27b4c678878c6ad157c7f0c1ab7.
Add manual column selection plugin

This plugin allows the user to choose which columns to display. The
columns are toggled per breakpoint based on the selection of checkboxes.
The selections persist for each individual breakpoint and the selections
for each breakpoint are independent of other breakpoints. Selections
will not persist across breakpoints.
