computefps: rename 'reduce.latarts' into 'disprel' to make it explicit that this form stems from the lattice dispersion relation and doesn't necessarily reduce the effect of lattice artefacts
fit.effectivemass: when resampling fails and columns are removed from the data because there are too many NAs, the inverse covariance matrix needs to be recomputed
analysis functions for pipi scattering
matrixfit: in dmatrixChisqr, do not forget first contribution to derivative
plot.effectivemass: fix palette mangling and use colours directly
