Next few commits will add requirement for "strongly typed" angles in all
function parameters, e.g.:
Matrix3::rotation(24.0_degf);
Math::sin(1.047_radf);
The purpose is to make angle entering less error-prone, e.g. not passing
degrees when radians should be etc.
Functionality present in Object is now split into three main components:
* Object itself, handling parent/children relationships
* Transformation implementation and interfaces for common functionality
* Object features, providing transformation caching and base for
cameras, collision shapes, rigid bodies etc.
Some functionality depending on former implementation is temporarily
disabled and will be reworked later.
SizeTraits class provides suitable types for given data size at compile
time, SizeBasedCall can call suitable templated overload based on given
data size at runtime.
Also added meta classes Pow and Log for computing powers and logarithms
at compile time, usable mainly in conjunction with SizeTraits. Their
implementation is checked at compile-time using static_cast().
