A tablewriter provides a Spartan but efficient way of writing data tuples into a table. It provides a plethora of STL-like insertion methods: it has insert() methods, push_back(), as well as an overloaded insertion operator (<<), and it supports inserters created by std::back_inserter(). All of these are templatized so you can use any container type or iterator range to feed tuples into the table. Note that in each case, a container or range represents the fields of a single tuple--not a collection of tuples.
