Soft dependencies

[janpecha]

• typehints in method/function parameters
• return typehints in PHP 7

$phpdepend->getSoftDependencies();
$phpdepend->getAllDependencies();
$phpdepend->getHardDependencies(); // alias for getDependencies()

For 2.x propably

$phpdepend->getDependencies(); // soft + hard
$phpdepend->getSoftDependencies();
$phpdepend->getHardDependencies();

or

$phpdepend->getRequiredClasses(); // soft + hard
$phpdepend->getRequiredClasses($phpdepend::SOFT);
$phpdepend->getRequiredClasses($phpdepend::HARD);
