Basics of the base PMC class set

[Dan Sugalski]

Just to let everyone know, I'm going to make a few minor changes to 
the repository over the next day or so. In addition to what's 
hopefully a sane example of using morph (which, granted, has a 
somewhat limited useful range, but...) I'm going to formally 
establish a basic set of parrot PMC classes. We're going to now have:

 Undef - The undefined value. Looks like 0, 0.0, false, or the empty 
string, depending on how you peer at it. Can transform into any other 
type. Assignment of an boolean, integer, float, bignum, or string 
turns it into a PMC of type Boolean, Integer, Float, BigNum, or 
String.

  Boolean - Basic true/false PMC
  Integer - Basic integer.
  Float - Basic floating point.
  BigNum - Basic extended-precision number
  String - Basic string
The Boolean, Integer, Float, BigNum, and String types (and yes, 
BigNum and String don't exist. Yet) maintain their types and 
autoconvert incoming data, Undef morphs itself to the destination 
type and goes from there.

These six types will form the basic scalar types for parrot. We'll 
work on formally defining them, then move on to the aggregate (hash & 
array) types and the IO & event bits. (And no, I've not forgotten 
events, IO, or (unfortunately) strings. I'm hoping to overwhelm Leo 
for when he gets back. Yeah, that's the ticket! :)
