* clarify documentation of import
Add a comment showing the equivalent python of the long example, and demonstrate how to get `from` and `as` on the same line.
* add python example comment in last import example
From the announcement <http://blog.readthedocs.com/securing-subdomains/>:
> Starting today, Read the Docs will start hosting projects from
> subdomains on the domain readthedocs.io, instead of on readthedocs.org.
[...]
> Projects will automatically be redirected, and this redirect will
> remain in place for the foreseeable future. Still, you should plan on
> updating links to your documentation after the new domain goes live.
- (Seemingly) accidental placement of a character meant that the backticks weren't picked up and displayed nicely.
- Everywhere you refer to 'Hy', it has a capital 'h'. Here it did not.
Fixed up minor grammar issue in one sentence
Fixed minor inconsistency with Python and Hy code
- Added variable assignment before code example
The `if` form now supports elif clauses.
It works like `cond` but without the implicit `do`.
The old `if` is now `if*`
variadic lif now supports "ellif" clauses.
Update if-no-waste compiler to use `if*` properly.
(Sometimes one character is all it takes.)
document if
reword truthiness
As part of the Grand Language Cleanup, a few examples in the tutorial
could be simplified:
* The --init-- function of the defclass example does not need an
explicit None anymore.
* The apply example in the Hy<->Python interop section can use a
keyword instead of a string in the last part.
This perhaps closes#971.

Adds a short (require) example, along with a few words on why macros can't be imported.
Closes#966.

This changes with syntax from (with [[x (expr)] (expr)] ...) to (with
[x (expr) (expr)] ...). Should have no ill side effects apart from the
syntax change.
Closes#852.

This changes let to use a flat list of symbol-value pairs instead of a
vector of vectors. One side effect is that (let [[a 1] z]) is not
expressible now, and one will explicitly need to set a nil value for z,
such as: (let [a 1 z nil]).
Closes#713.

apply now mangles strings and keywords according to the Hy mangling
rules (by using the same function, now imported from
hy.lex.parser). With this change, if the dict passed to apply has
keywords, strings or quoted symbols, they'll get mangled, to turn them
into proper keys.
This only works for the cases where the keys are directly in the apply
params. A previously deffed dict, or key through a variable will not be
mangled.
This closes#219.

Re-indent `fib` examples to match that in original blog post - "Indentation shall be two spaces, except where matching the indentation of the previous line"
Fixed up the documentation language here and there, related to the alias
removals in previous commits.
