Allow construct Neuron with named arguments.

Example:

<?php
$instance = new Neuron(stringValue: 'Hello world', integerValue: 50,
boolValue: false);

echo $instance->stringValue; // "Hello world" will be printed.
?>

Also, is possible to send infinite params without names and his names
will be numeric similar as a non-asociatie array, but as Neuron object.

Example:

<?php
$str = 'Hello world';
$int = 50;
$con = false;

$instance = new Neuron($str, $int);

echo $instance->{0}; // "Hello world" will be printed.
?>
