--------------------------------

Hi I'm Lahiru and I am a Computer Engineering student at University of Peradeniya, Sri Lanka.
I have good knowledge in following fields Data structures and algorithms, Python, C, C++,
java,...  I am interested in this gsoc project and I would like to contribute for the project.

> A Minimum Spanning Tree is a tree that spans all the vertices of a connected graph such
that the sum of the weights is minimum among all possible such trees. Finding Minimum Spanning
Tree on a large graph has many applications. MST algorithm is one of the basic graph algorithms.
Currently, Giraph has an implementation of Page Rank algorithm as part of its source code.
An implementation of MST algorithm will strengthen our use cases.
> Recently Mohsen Ghaffari et al. have shown that MST can be calculated in O(log* n) rounds
of communications in Congested Clique model [1]. Congested Clique have been shown to be the
impromptu distributed algorithmic model which has direct relations with Pregel. We can try
to implement the paradigm in Giraph.
