Added colors_coordinates_weighted models

This release adds the colors_coordinates_weighted models in the form of pytorch state dictionarys. We used the median class weighting for calculating the weights. See the paper for details.

Added decision tree models

This release adds the colors_coordinates and coordinates decision tree models. See the paper for details.

Added colors_coordinates models

This release adds the colors_coordinates models in the form of pytorch state dictionarys. In other words, the models expect the 6 features x, y, z, re, gr, blu for each point. See the paper for details.

Added coordinates models

This release adds the coordinates models in the form of pytorch state dictionarys.
