Saving figures with plot()

[Amit Saha]

This is something which was not obvious to me (or I don't read well),
so posting it in case it helps someone:

>>> from sympy import plot
>>> from sympy import Symbol

>>> x=Symbol('x')
>>> p = plot(2*x+3,show=False)

Now, you have a object of the Plot class returned in p.

So, you can either see the graph now:
>>> p.show()

Or save it:

>>> p.save('/tmp/foo1.png')

Yes, our documentation for plot() could be better (pull requests welcome!). Basically, plot(show=False) just returns the matplotlib object, and so you can call all the normal matplotlib functions on it.

A small correction: It is not a matplotlib object. However, if you use
the matplotlib backend
you can access the encapsulated matplotlib objects through `p._backend`.

Okay, I will try to go over the documentation for sending a pull
request and will try to make some small contributions.
