/*
* call-seq:
* Struct.new( [aString] [, aSym]+> ) -> StructClass
* StructClass.new(arg, ...) -> obj
* StructClass[arg, ...] -> obj
*
* Creates a new class, named by <i>aString</i>, containing accessor
* methods for the given symbols. If the name <i>aString</i> is
* omitted, an anonymous structure class will be created. Otherwise,
* the name of this struct will appear as a constant in class
* <code>Struct</code>, so it must be unique for all
* <code>Struct</code>s in the system and should start with a capital
* letter. Assigning a structure class to a constant effectively gives
* the class the name of the constant.
*
* <code>Struct::new</code> returns a new <code>Class</code> object,
* which can then be used to create specific instances of the new
* structure. The number of actual parameters must be
* less than or equal to the number of attributes defined for this
* class; unset parameters default to <code>nil</code>. Passing too many
* parameters will raise an <code>ArgumentError</code>.
*
* The remaining methods listed in this section (class and instance)
* are defined for this generated class.
*
* # Create a structure with a name in Struct
* Struct.new("Customer", :name, :address) #=> Struct::Customer
* Struct::Customer.new("Dave", "123 Main") #=> #<struct Struct::Customer name="Dave", address="123 Main">
*
* # Create a structure named by its constant
* Customer = Struct.new(:name, :address) #=> Customer
