Changelog

• push undefined to the array instead of null
• create a new array type called LuaArray
• add a custom inspect(), toString(), unshift(element), shift(element) to LuaArray
• LuaArray starts at 1 by default, but can include elements at 0, -1, etc. if manually assigned using array[0]
• LuaArray has a custom property of trueLength to get the actual length of the array
  • we can't override the length property as it is used internally by Node
