Bought this interesting looking tree / plant when I was at the local garden centre today (it was on a table with herbs on one end and a few sickly looking bonsai on the other - dare I call them that

). The tag calls it a neem tree but when I looked it up on the web I could not find any pictures that look like this fella.
The leaves on this one are compound (as far as I can tell there are no branches in the pic, just the trunk with compound leaves shooting out from it, obviously very young whatever it is). The pics I did find on the web all look to have sigle ovate leaves, resembling a ficus, not compound. The trunk is deep green with the portion that seems to be hardening off developing some beige striping...
Anyway, I'm at a loss as to what it might be. I'll treat it as a tropical for now unless someone out there recognizes it and can tell me what I actually have.
Come on now you wizards of botanical identification, don't let me down
