Without this patch applied there is no easy way to append one array to another. This is a problem because it is often desirable to join two arrays without flattening the contents into a single, one dimensional array. This patch addresses the problem by adding a `concat()` function which takes two arguments. The arguments will be concatenated together and a new array returned to the caller.

Appends the contents of array 2 onto array 1.

*Example:*
|
|
|
|
concat(['1','2','3'],['4','5','6'])

Would result in:
|
|
|
|
['1','2','3','4','5','6']
