* Concept from daniel.lucazeau@ajornet.com.
* @param db Adodb database connection
* @param tables List of tables to join
* @rowfields List of fields to display on each row
* @colfield Pivot field to slice and display in columns, if we want to calculate
* ranges, we pass in an array (see example2)
* @where Where clause. Optional.
* @aggfield This is the field to sum. Optional.
* Since 2.3.1, if you can use your own aggregate function
* instead of SUM, eg. $aggfield = 'fieldname'; $aggfn = 'AVG';
* @sumlabel Prefix to display in sum columns. Optional.
* @aggfn Aggregate function to use (could be AVG, SUM, COUNT)
* @showcount Show count of records
