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
