Example data for the Lab4IQM Mathematical Oncology module, read as "oncology:<file>",
e.g. growthfit("oncology:mouse_tumour.csv", t=day, V=volume_mm3).

All files are SIMULATED (made by tools/make_data.py in the source repository) to
illustrate Chapter 2 of Chaplain & Preziosi, Mathematical Oncology (Springer, 2025);
they are not measurements.

mouse_tumour.csv  calliper diameters of a subcutaneous tumour every 3 days, and the volume
                  pi a b (a+b)/12 (Sect. 2.2); truth: Gompertz, V0 = 20 mm^3, K = 1500 mm^3,
                  gamma = 0.12/day, 3% measurement error on each diameter.
spheroid.csv      diameter of a multicell spheroid in vitro over 25 days; truth: Bertalanffy,
                  delta = 0.25/day, K = 0.7 mm^3, 2% error.
glioma.csv        volume of an untreated low-grade glioma every 3 months (Sect. 2.7); truth: two
                  clones (2.38), gv = 0.04, gw = 0.2 /month, eps = 0.014, 0.1% aggressive cells, 4% error.
confluence.csv    cells per cm^2 growing to confluence (Sect. 2.9); truth: (2.53) with gamma = 1.45,
                  delta = 0.1 /day, eps = 0.6, rhobar = 2e5 cells/cm^2, 5% error.
