class ParagraphDef:
    '''
=================
Purpose
=================
Write paragraph definition tags.
States:
1. before_1st_para_def.
Before any para_def token is found. This means all the text in the preamble.
Look for the token 'cw<pf<par-def___'. This will changet the state to collect_tokens.
2. collect_tokens.
Found a paragraph_def. Need to get all tokens.
Change with start of a paragrph ('mi<mk<para-start'). State then becomes
in_paragraphs
If another paragraph definition is found, the state does not change.
But the dictionary is reset.
3. in_paragraphs
State changes when 'mi<mk<para-end__', or end of paragraph is found.
State then becomes 'self.__state = 'after_para_end'
4. after_para_end
If 'mi<mk<para-start' (the start of a paragraph) or 'mi<mk<para-end__' (the end of a paragraph--must be empty paragraph?) are found:
    state changes to 'in_paragraphs'
If 'cw<pf<par-def___' (paragraph_definition) is found:
    state changes to collect_tokens
if 'mi<mk<body-close', 'mi<mk<par-in-fld',
'cw<tb<cell______','cw<tb<row-def___','cw<tb<row_______',
'mi<mk<sect-close',   'mi<mk<header-beg',  'mi<mk<header-end'
are found. (All these tokens mark the start of a bigger element. para_def must
be closed:
    state changes to  'after_para_def'
5. after_para_def
'mi<mk<para-start'  changes state to in_paragraphs
if another paragraph_def is found, the state changes to collect_tokens.
