Optimize TaskScheduler - Githubissues

In a single-threaded scenario (function - runtime - explanation):

TaskScheduler::push - 10% - TaskScheduler::getDependency is O(n)
TaskScheduler::doTask - 20% - 10% is actual work, 5% because TaskScheduler::getParent is O(n), 2% on a std::find_if (O(n))
Task::Task - 10% - due to copying lambdas a lot (10.77% out of 10.87%)
