Print Line Table: Generate an HTML table report from array of data

This class generates HTML table reports from associative arrays with data that define the header titles and the contents of the rows.

It can:

- Display the first row with the titles of the columns
- Highlight rows with special colors when the user drags the mouse pointer over them
- Display links for given pages where eventually details may be presented about the information related to a certain row
- Display indented rows on which a given number of columns is cleared for instance in the case those columns contain the same data as in the previous row
