• Use polymorphism for nodes to simplify.
• Allow for multi-argument functions.
• Add support for operators "!" and "^".
• Improve expression handling for constants and variables.
• Add debugging utility.
• Change node function to use another class instead of ValueContainer.

Example

f(x) = x+2
g(x) = x+5

f(2)
>> 4
g(5)
>> 10
