* The idea:

* Document can provide one of the following information about text areas
|

|
|
* 1.) provide information for every character (best)
|

|
|
*
|
||
|
|
* 2.) provide information for every word
|

|
|
* We will use type Word for this kind of entity. It will store the
|
||
|
|
* word and should be followed by a type glyph which will contain some
|
||
|
|
* punctuation marks.
|
