Add a test case for the issue #55
Add lookbehind to visibility fixer

Checks that the character preceeding class|interface|trait is not a $,
as you may have a variable called $class, $interface, or $trait in
non-oop code.
Add test assertion for visibility regex fix

Ensures that non-oop code is left alone, even if it contains varaibles
names $class, $interface, or $trait.
added a version to composer.json
updated license year
Added support for reference parameters to PhpdocParamsAlignmentFixer
Better ControlSpacesFixer multiline indentation.

Before this fix, ControlSpacesFixer lost the indentation of multiline
if -control statement for outer closing parenthesis.

Before:
        if(true === true
            && false === false
        ) {
Became:
        if (true === true
            && false === false
) {

Now:
        if (true === true
            && false === false
        ) {

Commit also comments the regular expression with inline comment, so it's
easier to understand.

In ControlSpacesFixer::fixControlsWithParenthesesAndSuffixBrace()
(%s)[^\S\n]*\([^\S\n]*([^()]*?|(?R))[^\S\n]*\)[^\S\n]*{
Became:
(%s)[^\S\n]*\([^\S\n]*([^()]*?|(?R))[^\S\n]*(\s*)\)[^\S\n]*{

You should not exit by yourself, but return the return code.
See: https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Console/Application.php#L193 and https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Console/Application.php#L119

@lyrixx: Thanks for the comment. FIxed.

This is bad IMO. The goal of the fixer is to fix your code. So why would it be a failure when it does its job ?

It would make it a little easier to use in tests (CI, pre-commit hook). I would have no problem with adding a comand-line option `--check` to enable the return code. Please also see the discussion for the issue.

@stof I agree with you. But in this case, it's better to be pragmatic and don't respect the purity of code.

You can also made an analogy with grep:

``` bash
>[~/dev/foo](patch-2) grep foooooo web/index.php
>[~/dev/foo](patch-2) echo $?
1
>[~/dev/foo](patch-2) grep php web/index.php
Some content ...
>[~/dev/foo](patch-2) echo $?
0
```

If grep find something, it return 0, If not it return 1.
If php-cs-fixer find something it return 0, else it return 1. (Yes the pr do the opposite)

Fix spelling mistake

In `README.md` it should probably say `divided` rather than `devided`.
