// Of note: almost every darn thing on this page is wrapped in its own table.
// They went really overboard here... even the headers are their own tables.
// This is why there's a bunch of .closest('table') going on.

// *** Remove gratuitous line breaks. ***

// *** Remove the inventory sections ***.

// Hide the headers.
var inventoryHeaders = $('.h2view:contains("Inventory")').closest('table');

//Now hide the actual inventory tables.

// Since we only have one section remaining, hide the header for the real datasheet section.

// Easy way is to move the search refinement box down to where the link share box is.

// Find some bits of the DOM we need.
