| Description:
| This file defines the "concatenation" engine that joins
| together several (up to 10) fields. Its inputs are several
| multi-valued fields (automatic field conversion will do the
| right thing, so you can attach single-valued fields) of the
| same type, output is a multi-value field of the same type.
|
| If you need to concatenate more than 10 fields together,
| concatenate the outputs of several of these into yet another
| concatenate engine.
|
| Classes:
| SoConcatenate
