Description:


An abstract superclass for all unboxed integer classes.
In contrast to normal arrays (which store pointers to their elements),
unboxedIntegerArrays store the values in a dense & compact way. 
Since the representation fits corresponding underlying C-language representations,
these are also useful to pass bulk data to/from C primitive code.

Class protocol:

instance creation
o  new: size elementBitSize: nBitsPerElement signed: signedBoolean
return a new instance for size elements,
each holding an nBitsPerElement-sized integer.
With nBitsPerElement == 8, this returns a byteArray/signedByteArray,
with nBitsPerElement == 16, a word/signedWordArray
with nBitsPerElement == 32, an integer/signedIntegerArray
and with nBitsPerElement == 65, a longInteger/signedLongIntegerArray
Other sizes might be provided in the future.

Usage example(s):

     self new:10 elementBitSize:8 signed:false
     self new:10 elementBitSize:8 signed:true
     self new:10 elementBitSize:16 signed:true
     self new:10 elementBitSize:64 signed:true

queries
o  isAbstract
Return if this class is an abstract class.
True is returned for UnboxedIntegerArray here; false for subclasses.
Abstract subclasses must redefine this again.

o  isValidElement: anObject
return true, if instances of me can hold this kind of object


Instance protocol:

printing
o  printOn: aStream base: radix showRadix: showRadix
append a printed representation to aStream in the given number base.

queries
o  defaultElement

testing
o  isIntegerArray
return true if the receiver has integer elements.
These are Byte- and Integer arrays; both signed and unsigned
