The XML loader for the Humphrery Field Analyser (HFA) by Carl Zeiss Meditec
is essentially a XML parser that reads in the XML generated with the scientific
export license. The DICOMM loader is also a parser to read HFA data generated in a
DICOMM file. The loader for the Octopus perimeter by Haag-Streit is a csv reader
from files generated with the Eyesuite software. The parser also extracts information
on visual field pattern deviation values and normative values. The list that is returned
with the loadoctopus loader contains data frames which are structured with keys so that
redundancy is minimized (similar to a relational database). Detailed examples for
loadoctopus: https://huchzi.github.io/vf1/loadOctopus.html
