public class MD4 extends BaseHash
An implementation of Ron Rivest's MD4 message digest algorithm.
MD4 was the precursor to the stronger MD5
algorithm, and while not considered cryptograpically secure itself, MD4 is
in use in various applications. It is slightly faster than MD5.

public MD4()
Public constructor. Initializes the chaining variables, sets the byte
count to 0, and creates a new block of 512 bits.
