0) a) If starts before link & ends after a link, delete selection
	 b) If starts before link & ends at end of link (SelectedText ends with [END>), delete selection
	 c) If starts before link & ends between 2 links, (SelectedText ends with <START],
	 		push_selection; set SelectionStart1 = SelectionStart + SelectionLength,
	 		using SetSelection(SelectionStart1, 0) from TestWndProc/MyPanel.cs; insert space; pop_selection;
	 		allow deletion 
	 d) If starts at beginning of one link and end of another and end is in text:
	 	  Save SelectionStart & SelectionLength; Set SelectionLength=0; Insert a space; set SelectionStart
	 	  to saved SelectionStart+1 and SelectionLength = saved SelectionLength; allow deletion
	 e) If deleting a link do the following. 
	 
1) Break 'Rtf' into 3 pieces:
	 - From 0 to StartRtf
	 - From StartRtf to LengthRtf
	 - From EndRtf
	 
2) Capture any formatting from the link. 
   Only do this if selection starts at the 
   beginning of a link (using linklocation start)

Within piece 2 (link):
	Remove <START]
	Remove everything from first space on
	Take any remaining characters (formatting) and
		save them as FORMATTING to be used piece 1
		
3) Keep formatting and fix comment beginning/ending 
   based on single link or two in a row. 

Within piece 1 (before link):  
	if piece1 ends with [END>
		append FORMATTING+'\v0 ' after [END>
	else
		replace last \v with FORMATTING

4) Within piece 3 (after link):
  if piece3 begins with <START] 
  	insert '\v ' before <START] in piece3
	else if begins with '\v0 ' 
		remove '\v0 '
	else // remove '\v0' - this is in case other formatting exists
		remove first '\v0' found
