Density and sampling

Functions for computing density maps, sampling, and density matrix.

eye_density(): eye_density

get_density(): get_density

sample_density(): sample_density

density_matrix(): Compute Density Matrix for a Given Object

eye_density(<fixation_group>): Compute a density map for a fixation group.
