              Tree-like algorithms data structure 
               
             
             The algorithm tree structure is stored in text files. The tree 
              root is the name of the file. Newlines indicate branches of the 
              tree root. Sub-branches are implemented with newlines followed by 
              nesting tab(s); so on till the leaf nodes (see table tree_example_table).

                | Where a and b are the 1st level branches, a1 and b1 the 2nd 
                  level branches and a11 and b11 the leaf | 
               
             
             The selected algorithm is displayed in a new window. Branches 
              can be expanded to show sub-branches. The final leaf node will simply 
              not bring any further and is visualized in a different color (see 
              figure tree_pic).
