Loop-Genomics: Detect fusion genes

1. Step1: Load and Prep data
   1. Use either Load_blast_files.R OR
   2. data_prep.sh (this will internally call blast_files_save_in_RData.R )
2. Step2: Update blast files with genes and paired with shared molecules (pre_fusion.R)
3. Step3: Detect Fusion Genes (fusion.R)
4. Step4: For Visualization (fusion_plot.R)
