Update BuilderAbstract::normalizeValue() doc comment

Update lib/PHPParser/BuilderAbstract.php

Updated BuilderAbstract::normalizeValue phpdoc description.

Fixed some typos in the doc

Rename pSafe to pNoIndent

Matches the function more closely

Fix switch formatting

The switch cases were not indented and fall-through cases had an
unnecessary additional newline.

Patch by @pscheit (PR #39).

Better prededence and associativity handling in pretty printer

Previously the pretty printer added unnecessary and odd-looking parentheses
when several operators with the same precedence

Better prededence and associativity handling in pretty printer

Previously the pretty printer added unnecessary and odd-looking parentheses
when several operators with the same precedence were chained:

'a' . 'b' . 'c' . 'd' . 'e'
// was printed as
'a' . ('b' . ('c' . ('d' . 'e')))

Another issue reported as part of #39 was that assignments inside closures
were wrapped in parentheses:

function() {
$a = $b;
}
// was printed as
function() {
($a = $b);
}

This was caused by the automatic precedence handling, which just regarded
the closure as an ordinal nested expression.

With the new system the $predenceMap of PrettyPrinterAbstract contains both
precedence and associativity and there is a new method pPrec() which prints
a node taking precedence and associativity into account.

For simpler usage there are additional function pInfixOp(), pPrefixOp() and
pPostfixOp().

Prints not going through pPrec() do not have any precedence handling (fixing
the closure issue).

Turn rebuildParser.php into a CLI script

The paths are now more generic so it can be run from any directory, not
just grammar/.

Scalar_String::create() -> Scalar_String::parse()

Directly creating the node isn't necessary anymore, the token only needs
to be parsed. This makes it consistent with the other scalar pa

Scalar_String::create() -> Scalar_String::parse()

Directly creating the node isn't necessary anymore, the token only needs
to be parsed. This makes it consistent with the other scalar parsing
methods and removes the need to pass $arguments around.

Fix Switch subnode order

Not that it makes much of a difference, but could have caused issues with
"out of order" visiting of nodes.

Add support for expressions in empty (PHP 5.5)

Apart from the grammar modifications this also renames the Empty subnode
from var to expr. This breaks BC.

Adjust list and yield parsing, update prettyprinter

* nested list()s will now create nested List nodes (instead of just
nested arrays)
* yield $k => $v was parsed with key and v

Adjust list and yield parsing, update prettyprinter

* nested list()s will now create nested List nodes (instead of just
nested arrays)
* yield $k => $v was parsed with key and value swapped. This is now fixed
* the pretty printer now works with the newly added language constructs

Add support for constant dereferencing (PHP 5.5)

Examples: "foo"[2], [1, 2, 3][2]

Add support for yield expressions (PHP 5.5)

This adds a new Yield expression type, with subnodes key and value.

Add support for finally clauses (PHP 5.5)

This adds a new finallyStmts subnode to the TryCatch node. If there is
no finally clause it will be null.

Add support for list() in foreach (PHP 5.5)

Example: foreach ($coords as list($x, $y)) { ... }

This change slightly breaks backwards compatability, as it changes the
node struct

Add support for list() in foreach (PHP 5.5)

Example: foreach ($coords as list($x, $y)) { ... }

This change slightly breaks backwards compatability, as it changes the
node structure for the previously existing `list(...) = $foo` assignments.
Those no longer have a dedicated `AssignList` node; instead they are
parsed as a normal `Assign` node with a `List` as `var`. Similarly the
use in `foreach` will generate a `List` for `valueVar`.

Fix some doc comments

Change to SPDX License Identifier (BSD-3-Clause) for composer

The composer validate command is now supporting SPDX license identifers.

Fix parsing of `$foo =& new Bar;`

By-reference assignments of new expressions are now parsed as AssignRef
(instead of just Assign).

Closes issue #31.

Release PHP-Parser 0.9.2

Add installation instructions for different methods

Add note about xdebug.max_nesting_level

Add Class->getMethods() function

Add modifier accessors for ClassMethod etc

Fix test failures due to precision differences

Travis 5.2 seems to have changed the float output precision, so a test was
failing. Now the numbers in the expected output are also provided by PHP,
so they should be the same.
