properties access by name

Since rwproperty appears to use descriptors just like regular
property(), you'd do it the same way as for any normal attribute,
namely:

#for reading
print foo.y
#is the same as
print getattr(foo, "y")

#for writing
foo.x = 1
#is the same as
setattr(foo, "x", 1)


Cheers,
Chris
