Alessio Quaglino 6aabbc1892 Fixes an issue when self-attaching a model with pulley in tendons. 
The decision to attach a tendon is taken by looking at whether any of the elements in its path exist when the namespace is added to them. This does not work when pulleys are present so we need to ignore them in the count of unreferenced element.

Alessio Quaglino 7cdf180641 Introduce trilinear flex parametrization. 
These flexes use only 24 DOFs (3 per vertex of the bounding box), while colliding with the full high resolution mesh.

On an 8x8x8 cube, the performance using DOFs at all vertices is

```
 Simulation time      : 18.74 s
 Steps per second     : 533
 Realtime factor      : 0.53 x
 Time per step        : 1874.4 µs

 Contacts per step    : 114.88
 Constraints per step : 3322.51
 Degrees of freedom   : 1536
```

With the new implementation, it is the following:

```
 Simulation time      : 1.82 s
 Steps per second     : 5507
 Realtime factor      : 5.51 x
 Time per step        : 181.6 µs

 Contacts per step    : 38.84
 Constraints per step : 155.36
 Degrees of freedom   : 24
