Implemented dense tensorial Chebyshev kernel + add test, fixed some failing utests by comparing RELATIVE errors instead of absolute.

Fixed handling of non homogeneous kernels of interactions (aka matrix kernel) in Uniform kernel (TODO Fix in Chebyshev if relevant), Introduced blockwise evaluation of tensorial matrix kernel (+redesign precomputation), added input parameter in AbstractUnifKernel (for OptiDis non singular Ra_{ijk} or any matrix kernel requiring an extra parameter), +divers test fixing.

Introduced tensorial physical value, potential and force (through templatization of P2PParticleContainer with dimensions NRHS and NLHS, default NRHS=NLHS=1). ChebTensorial kernel does not support this yet (TODO apply same modif on ChebInterpolator).

Implemented a tensorial version for ChebyshevSym kernel (currently in separate files for clarity/safety, TODO finalize and merge), cleaned up tensorial Uniform kernel.

ommit.

A new loader to load results files, an example of its use, a test file for the class, and an exec to create results files have been added
