SPA Simple Paging Class: Display MySQL query results split in pages

This class can be used to display MySQL query results split in multiple Web pages.

It can take a given SQL query or the name of a table to be queried and computes the total number of results that it would return.

The class takes the limit of query results to display and the number of the current listing page, and returns the SQL query string with a limit clause to retrieve only the range of records that should be listed in the current page.

The class also generates links to browse between the different query results listing pages.
