Check optional metadata fields before
trying to display them.

load new results when the bottom of the page
is near.

Previously, when the pages had a height
smaller than the screen's height,
the footer was displayed somewhere in the
middle of the page.

Display the footer at the bottom, with
no whitespace after it.

Pass a SearchInput object to the back-end
and display the data, which is returned as
a SearchResultDTO.

The previous implementation starting
at testData/, which is in the same directory
as the Java file where the path is used
did not work for me.

This component contains the search input fields.

- Make footer full width and put it at the bottom.
- Replace light blue bar below the navbar
  with white bar, to match the bar above the footer.

Exercise cards are useful in multiple places,
so they should be displayable by an independent
component.

The CSS for making the cards have the correct
width and height is very finicky and took a long
time to get to work. The current styling should
be refactored.

At the moment, we only treat exercises as search results,
but exercises can also appear in other context,
e.g. as bookmarked exercises.

For this reason, it makes more sense to describe them
using the more general term "Exercise".
