The `list` function is used for taking all input values and putting them into
a single `List` as response.
For example if the message body contains '4' then `${list(1,2,3,$\{body})}`
will return a list with 4 elements. `[1,2,3,4]`.
+You can also add and remove from `java.util.List`(s). For example if the
message body is a `List` then you can add
+something `${listAdd('Hello')}`. This will add to the message body. The source
can also be an expression instead
+of the message body, such as a variable:
`${listAdd(${variable.myVar},'Hello')}`.
+To remove from a list, you use `${listRemove('Hello')}`, or use a number to
refer to the position `${listRemove(0)}`.
+Use _last_ as a special index to remove the last element:
`${listRemove(last)}`.
+
The `map` function is similar to the `list` function but for creating a `Map`
instead where the values are grouped in pairs 2 by 2.
For example `${map(1,a,2,b,3,c)}` will return a map with 3 elements `{1=a,
2=b, 3=c}`.
