Detailed Description

Keep track of the progress of tasks and subtasks.

Not thread safe. Could easily be made thread safe, though. See "Thread safety" comments in the source code.

Usage Example:

Progress p1(5.0);
assert(p1.getNormalizedProgress() == 0.2);
assert(p1.getNormalizedProgress() == 1.0);

Progress p2(10.0);
    Progress p2_1(10.0);
    p2.addSubProgress(&p2_1, 5.0);
    assert(p2.getNormalizedProgress() == 0.0);
    assert(p2_1.getNormalizedProgress() == 0.5);
    assert(p2.getNormalizedProgress() == 0.25);

// When the sub progress gets destroyed, the parent
// assumes it is completed.
assert(p2.getNormalizedProgress() == 0.5);
