Actually, the right place to do this work is in the Java code that creates
the "model" that we pass to Freemarker. (Yeah, it is kind of complicated.)
Freemarker uses the classic MVC model. The template is the view. Java
builds the model. (Let's ignore the controller for now.)
For an example, look in `ProfileResources.java`, which is in this PR. Look
at the `ProfileInfo` class. Here we gather up the bits of information we want
to display on the web page. Any calcs needed to prepare the data are done here.
Then, Freemarker simply pulls out the pre-created data using the getter methods.
So, the `ProfileInfo` class could be extended to have, say, the raw
duration in ms along with methods to return the computed values:
`getDisplayDuration()` and `getDurationUnits()`.
