This commit is the PCA-TELLIE monitoring section for Minard. It requires a soft-link 'generated' inside the static/ directory which should point to the directory that contains the images that are generated by the PCA monitoring code.
Same as below, it's not a big deal, but keeping the formatting inside the template makes it clear what is happening, i.e. you can find out what the function does without opening up a separate python file.
