Feature: Vector to Columns
JIRA: MADLIB-1240
The vec2cols function enables users to split up a single column into
multiple columns, given that the input column contains array entries. For
example, if the input column contained ARRAY[1, 2, 3] in one of its rows, the
output table will contain 3 different columns, one for each element of the
array.
