A simple class that allows to visualize segment trees in the terminal.

• Download the source file (named st_printer.cpp).
• Put it inside of your current work directory.
• Instantiate a TreePrinter object with the type of your node as its template parameter.
• Invoke the print function of said object with the specified parameters:

• Include the file when compiling. For example, if you want to compile a file named "main.cpp", compile it with "g++ main.cpp st_printer.cpp".
• NOTE: this step seems unnecesary, use it only if normal compilation isn't working.

• Create a static function that takes a single argument with the same type as the nodes of your segment tree and returns a string.
