<!--- To add functions...
addRecord()
deleteRecord()
updateRecord()
filter()
isFiltered()
clearFilter()
columnType()
isQuotedColumn() ...this would be used to know if query interaction for
this type of column requires quotes or not, could help automate dynamic queries
sort() ...note-not sure if QofQ can do a multicolumn sort
addDynmicColumn() ...i.e. "dynamically calculated columns" that return as
standard data columns. (and in CFMX7 you can have data types for these)
getRecordRange(start,end)
