'*** A simple MsWord->Markdown replacement macro by Kriss Rauhvargers, 2006.02.02.
'*** This tool does NOT implement all the markup specified in MarkDown definition by John Gruber, only
'*** the most simple things. These are:
'*** 1) Replaces all non-list paragraphs to ^p paragraph so MarkDown knows it is a stand-alone paragraph
'*** 2) Converts tables to text. In fact, tables get lost.
'*** 3) Adds a single indent to all indented paragraphs
'*** 4) Replaces all the text in italics to _text_
'*** 5) Replaces all the text in bold to **text**
'*** 6) Replaces Heading1-6 to #..#Heading (Heading numbering gets lost)
'*** 7) Replaces bulleted lists with ^p *  listitem ^p*  listitem2...
'*** 8) Replaces numbered lists with ^p 1. listitem ^p2.  listitem2...
'*** Feel free to use and redistribute this code
