Query Builder for layers.
The query builder allows interactive creation of a SQL for limiting the
features displayed in a vector layer. The fields in the table are
displayed and sample values (or all values) can be viewed to aid in
constructing the query. A test function returns the number of features that
will be returned.

%End

%Docstring
This constructor is used when the query builder is called from the
vector layer properties dialog
:param layer: existing vector layer
:param parent: Parent widget
:param fl: dialog flags
%End

%Docstring
The default implementation tests that the constructed sql statement to
see if the vector layer data provider likes it.
The number of rows that would be returned is displayed in a message box.
The test uses a "select count(*) from ..." query to test the SQL
statement.
