Mainly contains a plotting function ggseg3d(),
and data of two standard brain atlases (Desikan-Killiany and aseg).
By far, the largest bit of the package is the data for each of the atlases.
The functions and data enable users to plot tri-surface mesh plots of
brain atlases, and customise these by projecting colours onto the brain
segments based on values in their own data sets. Functions are wrappers
for 'plotly'. Mowinckel & Vidal-Piñeiro (2020)
