Detailed Description

The class which parses text zones in a pc MS Works document v1-4.

This class must be associated with a WPS4Parser. It finds and reads:

TEXT[3] : the text limits ( header, footer, main text with notes)
SHdr, SFtr : a string to store header/footer in v1-2 (?)
BTEC : the fonts properties
BTEP : the paragraph properties
FONT : the font names
FTNp, FTNd : the footnote positions (text position and text of notes)
BKMK : a comment field ( contain a string )
CHRT : a chart ( unknown format ) It reads:
DTTM : field contents ( only parsed)
EOBJ : the text position with the position and size of an object

Note:: It also reads the size of the document because this size is stored between the "entries" which defines the text positions and the BTEC positions...
