Terminal
This is a CLI (command line interface) way to communicate with AngouriMath.Interactive. The "language" of communications is F#: great functional-first .NET language.
The terminal itself is made with Spectre.Console, Radline, and dotnet/interactive.
As an example of what you can do in it, see a Jupyter notebook, demonstrating the AngouriMath.Interactive package.
By default it applies aggressive operators which override the +, -, *, /, ** operators for any pair of object. This is not an F# console, but AngouriMath terminal, after all.
