8b64195cf2 Try .17G print if .16G is not enough 
This should be enough for all cases, because: A double has 53 bits
of mantissa (including the implicit 1 bit), which is 53*ln(2)/ln(10)
= 15.95 decimal digits. However the leading decimal digit may encode
less than the usual 3.32 bits, which will push this over the edge to
requiring 17 decimal digits.

3b7d8e8b5d Enable basic error recovery 
Adding only a single recovery rule for now.

The API is now:
 * throwOnError parser option must be disabled.
 * List of Errors is available through $parser->getErrors(). This
   method is available either way.
 * If no recovery is possible $parser->parse() will return null.
   (Obviously only if throwOnError is disabled).

a6d2cd69f8 Clarify attribute assignment code 
* Don't assign to attribute stack on reduce - why was that there

* Assign attributes to the position in the stack where the first
token of the production is, instead of one position earlier.
* Add a comment to clarify why we also assign attributes on read,
instead of just on shift.

6996db1e3a Build node attributes inside semantic action methods 
Minor performance improvement for parsing, also allows to access
attributes with higher granulity in the parser, though this is not
currently done.

* #n can now be used to access the stack position of a token. $n
  is the same as $this->semStack[#n]. (Post-translate $n will
  actually be the stack position.)
* $attributeStack is now $this->startAttributeStack and
  $endAttributes is now $this->endAttributes.
* Attributes for a node are now computed inside the individual
  reduction methods, instead of being passed as a parameter.
  Accessible through the attributes() macro.

e4eab9ec0c Simplify code 
The new class couldn't already exist at that point - if it did, the
old name would have been aliased already and the autoloader wouldn't
trigger.

6aaa87f143 Fix PHP 7 alias registration 
This fixes the case where the old name is used before the new one
is ever used, e.g. when manually constructing nodes, as opposed to
parsing them.

The previous approach would try to register the alias from OLD to
NEW. This would trigger autoloading on NEW and afterwards it would
register the alias from OLD to NEW. Afterwards the alias registration
which originally triggered the autoload would run, thus redeclaring
the class.

TL;DR aliases suck, closes #192.

a2d7e8977a Use real properties for storing subnodes 
Instead of storing subnodes in a subNodes dictionary, they are
now stored as simple properties. This requires declarating the
properties, assigning them in the constructor, overriding
the getSubNodeNames() method and passing NULL to the first argument
of the NodeAbstract constructor.

[Deprecated: It's still possible to use the old mode of operation
for custom nodes by passing an array of subnodes to the constructor.]

The only behavior difference this should cause is that getSubNodeNames()
will always return the original subnode names and skip any additional
properties that were dynamically added. E.g. this means that the
"namespacedName" node added by the NameResolver visitor is not treated
as a subnode, but as a dynamic property instead.

This change improves performance and memory usage.

an array would due to incorrect usage of the API (e.g. array instead
of variadics).

d774dbc1b7 Add optional startFilePos and endFilePos attributes 
The lexer can now optionally add startFilePos and endFilePos
attributes, which are offsets in to the lexed code string.

The end offset currently points one past the last character of
the token - this is pending further discussion.

The attributes are not added by default and have to be enabled
using the new 'usedAttributes' lexer option:

	$lexer = new Lexer([
		'usedAttributes' => [
			'comments', 'startLine', 'endLine',
			'startFilePos', 'endFilePos'
		]
	]);
