PWD works fine, BUT since the folder is watched by an abstraction, not
by the parent PWD only returns the parent value. According to Miller
there is no way to get the path an abstraction was loaded from. So the
path has to be in a standard place. in TOT I think this had to be
absolute due to ~ replacement, but I see in python we can do ~
replacement so I should be able to get the home directory path.

What I'm worried about is reading abstractions from two different places
into one array... at the moment I'm just thinking of concatenating the
two lists (with absolute paths) and just ignoring the fact they come
from different places.

I don't know how the ; pd-abstraction.pd stuff will work with possible
duplicate names... Also its harder (impossible) to open pixelTANGO
abstractions as a basis of new user contributions (since they would be
burried down in the .app.)
