restart scanner

In some cases - like formula speadsheet, lexer is not an instance but just an 
restart of existing class - singelton, tokenise formula and forget the rest
It wold be nice to see this behaviour in plex.

Currently i have a workaround :

class Scanner:
  trace = 0

  def __init__(self, lexicon, stream, name = ''):
    self.lexicon = lexicon
    self.name = name
    self.reset(stream)

# static variables should be initialized per scan -  not per instace

  def reset(self, stream):
    self.stream = stream
    self.queue = []     # list of tokens to be returned
    self.initial_state = None   # Node
    self.buffer = ''
    self.buf_start_pos = 0     # position in input of start of buffer
    self.cur_line = 1          # line number of current char
    self.start_pos = 0         # position in input of start of token
    self.start_line = 0        # line number of start of token
    self.start_col = 0         # position in line of start of token
    self.text = None           # text of last token read
    self.state_name = ''       # Name of initial state
    self.begin('')
    self.next_pos = 0       # position in input of next char to read
    self.cur_pos = 0        # position in input of current char
    self.cur_line_start = 0 # position in input of start of current line
    self.cur_char = BOL
    self.input_state = 1

Problem Building Plex-2.0.0dev on WinXP 32 Bit w/Python

Hi,
I have downloaded Plex-2.0.0dev, and the following dependencies:
nose-1.3.0
pygments-1.6
docutils-0.11
markupsafe-0.18
jinga2-2.7.2
sphinx-1.2

I have successfully installed all the dependent modules using the standard 
"setup.py install" command.

There are unfortunately problems with building plex (see attached file).
