#17 Improve Documentation

[Chris M]

Hi,
Please could you improve documentation arounf custom function handlers. Specifically I can't get enough info from the existing documentation to figure out how to allow a query to call a method in a custom object.
For example using Collection ConcurrentHashMap<String, Order>

and String sqlStatement = "Select * from xxx.Order where " +
" getData('basket') like 'AAA%' and "
+ " getData('client') like 'AAA%'";
a query parse exception is thrown....
