Append the prologue statement to the beginning of for loop

See #60.
Remove newline from statement code generation

If you have a single statement String with a new line, e.g.

b.blah = blah; NEWLINE

then calling ASTNodeFactory.newStatement(…) will generate an ugly BLOCK

{
b.blah = blah; NEWLINE
}

To eliminate the BLOCK, you must not include the NEWLINE.

See #60.
Reorder how the channels are displayed

Previously they were wrongly displayed in reverse order.

See #57.
