Concat-Groups
DESCRIPTION
Links two groups of data together in a series, allowing duplicate information to appear from both groups.
For example, group A contains the elements u, v, and x and group B contains the elements x, y, and z. The Concat-Groups webject links the elements of groups A and B together, one after the other, to form group C. Group C would then contain the elements u, v, x, x, y, and z.

</MyClassName>
The default for this parameter is “Unknown-Class-Name.” This parameter is optional.
GROUP_IN
Specifies the two or more groups that are used in the concatenation. This parameter is required.
