Relation:relation

Defines a new relation and puts it on the stack.

relation namelist

example	comment
`relation film, director`	relation with 2 columns
`relation employee, id, name, familyname`	relation with 4 columns
`relation`	valid relation, though not very useful
`relation foo, bar insert 2,5 insert3,4 insert 6,8`	new relation with 3 columns and 3 rows

The relation itself has no name.

The instruction is used to create data ad hoc and to pupulate it with the insert or the data instruction.

You will not see the relation in the notebook unless you print it.
