IterPrinter: A simple iteration history printer

When using iterative numerical algorithms it is common to print after each iteration a message so that a user can monitor convergence and catch any bugs. For example, in the demo.py file

 iter │   b - a    │    f(c)    │        a         │        b         │
──────┼────────────┼────────────┼──────────────────┼──────────────────┤
