Functions like Godot's built-in `Expression` class with the flexability of an actual script.

See the `tests/` directory for more examples.

## Example

```GDScript

var ae = preload("res://addons/advanced-expression/advanced_expression.gd")

# Add variables

# Currently, variables must be preinitialized with a value since,

# in the author's opinion, variables should avoid being null when possible

ae.add_variable("counter").add(0)

# Add function with a parameter

ae.add_function("increment") \

	.add_param("input: int") \

	.add("return input + 1")

# Add runner code that will be run on execute

# Follows the same semantics as regular functions

ae.add() \

	.add_param("starting_value") \

	.add("counter = starting_value") \

	.add("for i in 5:") \

	.tab() \

	.add("counter = increment(counter)") \

	.add("return counter")

# Everything must be compiled before executing

if ae.compile() != OK:

	push_error("Failed to compile")

# Parameters must be passed as an array

# These are passed to the runner function

assert(ae.execute([1]) == 6)

```
