'Diversity' computation should replace the pre-calculated weight_1_2 values

[HeesukSon]

In ModificationProbTree.java, Diversity computation is not reflected when assigning weight_1_2 values:

private void computeWeight_1_2(){
	Domain domain = ConfigUtil.getInstance().domain;

	if(domain == Domain.SDP){
		this.root.updateOutEdgeWeight(Functionality.PROTOCOL_BASIC_INFO.toString(), 0.577f);
		this.root.updateOutEdgeWeight(Functionality.CONTENT_PARSING.toString(), 0.451f);
		this.root.updateOutEdgeWeight(Functionality.PROTOCOL_BEHAVIOR.toString(), 0.662f);
		this.root.updateOutEdgeWeight(Functionality.SESSION_MGMT.toString(), 0.239f);
	}else{
		int cp_cnt = 0;
		int ss_cnt = 0;
		int prot_basic_info_cnt = 0;
		int prot_behav_cnt = 0;
		int sum = 0;

		for(MessageFieldUpdate update : kb.getUpdateHistory()){
			if(update.getFunc().equals(Functionality.CONTENT_PARSING)){
				cp_cnt++;
				sum++;
			}else if(update.getFunc().equals(Functionality.SESSION_MGMT)){
				ss_cnt++;
				sum++;
			}else if(update.getFunc().equals(Functionality.PROTOCOL_BASIC_INFO)){
				prot_basic_info_cnt++;
				sum++;
			}else if(update.getFunc().equals(Functionality.PROTOCOL_BEHAVIOR)){
				prot_behav_cnt++;
				sum++;
			}
		}

		this.root.updateOutEdgeWeight(Functionality.CONTENT_PARSING.toString(), (float)cp_cnt/sum);
		this.root.updateOutEdgeWeight(Functionality.PROTOCOL_BEHAVIOR.toString(), (float)ss_cnt/sum);
		this.root.updateOutEdgeWeight(Functionality.PROTOCOL_BASIC_INFO.toString(), (float)prot_basic_info_cnt/sum);
		this.root.updateOutEdgeWeight(Functionality.PROTOCOL_BEHAVIOR.toString(), (float)prot_behav_cnt/sum);
	}
}

This hardcoded weight value computation is written to save time for SDP case study experiment and should be replaced.
