To fix bug 181681, Model needs a method to parse current expressions in data binding into following components:

expression      String  Javascript expression. For Aggregation, this is the
expression to be aggregated over.

aggregateFunction       String  For Aggregations, this is the name of the
function (e.g., “Sum”, “MovingSum”, etc.). For non-aggregate bindings, this
property and all subsequent properties are empty.

Args    List of Expressions     Additional arguments to the aggregate function
(optional).

Filter  Expression      Aggregate filter expression (optional)
