Remove lab directory

Fix bug in Python interpreter

Remove now useless dependency to HPP-MODEL_URDF and METAPOD

METAPOD is now outdated.
Installing it on recent platforms is now tedious.
The results was only compared for Symmetric3 class.

As HPP relies on Pinocchio since 2 years, it seems natural to remove the dependency.
Check and benchmark are no more meaningfull.

Add version utils to check the current version of Pinocchio

This feature mimics the Eigen checking of version

Update benchmark

Update function name when considering joint Jacobian

This provides some useful information for end users

Some functions working on Jacobian have been renamed:

- getJacobian is now getJointJacobian
- computeJacobians is now computeJointJacobians
- getJacobianTimeVariation is now getJointJacobianTimeVariation
- computeJacobiansTimeVariation is now getJointJacobianTimeVariation

[LieGroups] Replace Jintegrate by dIntegrate_dq and dIntegrate_qv

Split CRBA and centroidal algos

[C++] Add Jexp3 and Jexp6
