New issue 3331 by krastano...@gmail.com: use unicode names instead of hex
encoding
http://code.google.com/p/sympy/issues/detail?id=3331
The code will be much more readable if we use unicode names in literal.

Anyway, there is a handful of strings both in tests and in code that just
use the unicode hex value. I will leave this open. Maybe it will get

functions -- speed issue

I've found one thing that drops the time down by an order of magnitude. It
still takes a long time, simply because there are 500500 terms

This method just invokes iteritems on the underlying dictionary. Having
`iteritems` is useful for efficiency reasons.

Previously those classes were pretty printed using long Unicode symbols,
which worked erratically on different terminals. This commit uses more
standard characters.
Things are now printed like this:
```
{g∘f:A₁——▶C₁: ∅, id:A₁——▶A₁: ∅, id:B——▶B: ∅, id:C₁——▶C₁: ∅, f:A₁——▶B: ∅,
g:B——▶C₁: ∅}
