The StreamTokenizer class can tokenizer a Reader into
tokens. For instance, in the string "Mary had a little lamb"
each word is a separate token.

We need to move through the tokens in the underlying Reader
by calling the nextToken() method in a loop. After each
call to nextToken() the StreamTokenizer has several fields
you can read to see what kind of token was read, it's value
etc. These fields are:

ttype The type of token read (word, number, end of line)
sval The string value of the token, if the token was a
string (word)
nval The number value of the token, if the token was a
number.
