Main program execution:

	Execute any rune file by using the provided shell script:
		rune.sh [file]

	How to execute the test problem:

		The test problem is executed through the using the make file:
			make run-problem

		To change the input values of the full adder, change the values of the signal
		in at lines 215, 216, and 217.

Rune is similar to python in the sense that statement blocks are grouped using whitespace. Currently a tab is also equal to 4 spaces and they can be used interchangably. 

	if (x > 10):
		print("BLAH")

	var c = func(y):(

		while (x < 100):
			x += 1
	)

Literals:
	Integers : [0-9]+
	Double : [0-9]+.[0-9]+
	Strings : "[^(/")]*"
	Null : null

Variables:
	Variables are declared with the var keyword
		var IDENTIFIER
	Or
		var IDENTIFIER = Expression

	Multiple variables can be declared at once and all variables not initialized to a default
	value are set to null.

		var IDENTIFIER, IDENTIFIER, ... = Expression, Expression, ....

	Variables cannot be redeclared in the same scope

Assignment:
	Variables can be reassigned to using the =, +=, -=, /=, and %= operations.

		IDENTIFIER += Expression

	Multiple can also be assigned to as well but the number of expressions and identifiers
	must be equal.

		IDENTIFIER, IDENTIFIER, ... += Expression, Expression...

Functions:
	Functions are defined with the func keyword.

		func(PARAMATERS, PARAMATERS, ...):(
			BODY
		)

	A function with a single line body can be defined like:

		func(PARAMATERS, PARAMATERS, ...):BODY

	So to set a function to an identifier, one would od:

		var IDENTIFIER = func(PARAMATERS, PARAMATERS, ...):...

	To return a value or multiple values, 

Conditionals:
	If statements can be represented like: 

		if (Expression):
			BODY
		else if (Expression);
			BODY
		else:
			BODY

	Boolean expressions and and or are short circuit evaluated

Iteration:
	While statements can be used like:

		while(Expression):
			BODY
Strings:
	You can concatenate values to strings using the + operatior

		println("Hello my name is "+ name+" and I am "+age+" years old")

Arrays:
	Arrays objects can be created through syntax or through the array function call.

		var a = [1, 2, this, 4, "Hello", 6]

		var b = array(10) //Initialized to a size of 10 filled with nulls

	Arrays can be accessed using brackets and the first index starts from 0.

		print(a[0]) //prints 1
		print(a[4]) //prints Hello

		print(b[0]) //prints null because arrays spots are initialized to null


	Arrays have a length member that gives the size of the array.

		print(a.length) //prints 6
		print(b.length) //prints 10

Objects:
	To return the environment, use the this keyword

		var MyObject = func(x):(
			return this
		)

	Members of an object can be reassigned to and retrieved with the dot operator

		var m = MyObject(5)
		println(m.x) //prints 5

		m.x = 10
		println(m.x) //prints 10

Print:
	Print a string representation of an object using print or println functions.

		println("blah", 1, [8,3, 4])  //Prints them all in the same line then goes to the next
		print(1, "something"), 9.0)
