// calltree.sc
// -----------
//
// Suchakra Sharma <suchakra@shiftleft.io> (2019)
//  
// Prints the complete call-tree with all possible branches starting from the top of the input method. It is recommended to increase
// the max steps per query to a higher number (eg. "config.query.maxStepsPerCallQuery = 1000000L") for better results.
//
// Example Usage:
//   ocular> import $file.scripts.calltree
