+ * Make interface '''TextProcessor'''. 
+  * Usage: Gets a text on its input and gives another text as a result. Processors get the model text of an element and make it ready for drawing, that is, they may put decorations, colors, may even change the text itself.  
+  * Contents: 
    * Empty interface '''Options'''. This is the criteria for processing the text, e.g. highlight color, caret position, highlight interval, etc.
    * Interface '''Effect'''. This consists of the resulting text after a processing and the change that is generated from it (the change that if applied to the raw text, the processed one will be the result). An Effect is actually an instruction for the next processor in a processing chain.

  * Implement text search processor
-
+  * Usage: It is intended to draw the background highlight for the current quick search result. Since selection will also use a TestProcessor, the highlights() property somewhere in the text frame view, becomes unneeded. The quick search logic should stay unchanged, but the results will not be put in the highlights() property - they will be set as current options for the search processor. 
+  * Contents:
+   * TextSearchOptions - they only contain the HotTextInterval for the highlight and the highlight color.
  * Implement text link processor
+  * Usage: The current text model has attributes with link Ids attached to the text units. The processor needs the colors associated with these IDs so it can set the text foreground - this way, the text will be drawn with different color in its link intervals
