> Project: Optiq
> Issue Type: Bug
> Reporter: Julian Hyde

>
> Add tile and measure elements to the lattice model element. This will allow
> the model author to define tiles (materialized aggregates) as part of the
> lattice definition.
> Each tile has a list of dimensions (each of which is a column of the lattice)
> and a list of measures (each of which is an aggregate function applied to
> zero or more arguments, each of which is a column of the lattice).
> The lattice has a default list of measures; this is used by any tiles that do
> not specify a measure list explicitly.
