[mlpack] Regarding long term project

[Nilay Pochhi]

Greetings!
I am new to MLPack and to open-source development in general. The
project which enticed was to implement various tree types (given here:
https://github.com/mlpack/mlpack/wiki/SummerOfCodeIdeas#implement-tree-types).
I'll be trying to implement segment trees as I have hands on
experience working with them. Which methods do I need to implement?

Warm Regards,
Nilay
