A consistent set of tools to perform in-database analytics
on Teradata Aster Big Data Discovery Platform. toaster (a.k.a 'to Aster')
embraces simple 2-step approach: compute in Aster - visualize and analyze
in R. Its `compute` functions use combination of parallel SQL, SQL-MR and
SQL-GR executing in Aster database - highly scalable parallel
and distributed analytical platform. Then `create` functions visualize

labeling, and others are supported with most visualizations.
