Unfortunately, easymesh code still relies heavily on its specifics, so I’m
letting it live as lol::easy_array for the near future. But it’s going away.

This lets us use the code for non-float variable types. I also got
rid of the mat4-to-quat code so that users are forced to use the
mat3-to-quat code and possibly discover places where their code is
suboptimal.

The containers no longer force the user to use the ptrdiff_t type for
size information. For convenience, size() now always returns an int,
and the size_s() method offers a way to handle arrays with more than
2 billion elements. Internally, we still use ptrdiff_t, though.

Since so much code had to be changed, I took the opportunity to get
rid of capitalised accessors for classes that are lowercase.

MASK to SWIZZLE in the vector templates, rename matrix<> to mat<> for
consistency, implement transposition for all matrix sizes, make matrix
columns private and only accessible through operator[].

- fixed 1270 CR characters
 - fixed 56 trailing spaces
 - fixed 5085 tabs

Added RayCastResult & a naïve integration for EasyCharacterController.
Enjoy !

Indeed

Character integration better but still not working.

Small tweaks in the BtPhysTest demo.
Added Ghost Object skeleton (not tested)

+ Constraint hollow class.

+ weird racist test : the primitives only collide with their same type.

Phys::Simulation is now an entity.
Phys::Simulation now implements timesteps correctly.

Added several delete/destructor, speeds up exit & saves memory.

EasyPhysics : Added Cone primitive.

Added lol::phys::Simulation, lol::phys::EasyPhysics for easy physic uses.
Added PhysicsObject, wich hold EasyMesh & EasyPhysics components so it is easy to use. Easy seems to be the consensus.
BtPhysTest now works with new physics classes.

Known problem for this commit:
Physics is not properly setup.
There might be memory leaks, I don't think I've parsed all new/delete.
A LOT of primitives are not taken into account.
