Refine Architecture to Improve Extensibility

Agora Blockchain is a decentralized platform for conducting elections. Agora is a library of voting algorithms like Moore's, Oklahoma etc. Some of these voting algorithms are already implemented by AOSSIE in a centralized manner using Scala as their backend. The current version of the DApp has only one voting algorithm - General. The idea is to extend support to other electoral systems - Majoritarian, Preferential(Oklahoma), Plurality etc. and result computation algorithms like Moore.
