We presented some of the main concepts that should be useful in understanding the existing problems and improving past results. Many of these concepts already form the basis for analysis of related past work the experiments carried out throughout this work. Some of the weaknesses of previous work have been identified and advancements or alternatives have been suggested. The suggestions listed are slightly ill-considered in the sense that they have not been fully thought through and whether they will work or not is a question that will be answered as the project moves ahead. Real alternatives will be revealed once the work reaches its set milestones and is considered successful. Many more challenging issues are sure to come up and the work will most possibly have aims that cannot necessarily be achieved. Any contradiction to this assumption will make this work valuable.
