Implement Namespaces

[Alexius-Huang]

What?
Namespaces for storing constants and functions.

Why?
Organizing code.

How?
Sample Wyrd Code

namespace Rectangle
  Num sides = 4
  def area(width: Num, height: Num): Num => width + height
  def circumference(width: Num, height: Num): Num do
    (width + height) * 2
  end
end

Rectangle::sides
Rectangle::area(4, 5)
Rectangle::circumference(4, 5)

Compiled Result

const ns_Rectangle = {
  sides: 4,
  area: function (width, height) {
    return width + height;
  },
  circumference: function (width, height) {
    return (width + height) * 2;
  },
};

ns_Rectangle.sides;
ns_Rectangle.area(4, 5);
ns_Rectangle.circumference(4, 5);

Namespaces currently should only support ConstDeclaration and FunctionDeclaration
