Introduced core width in R_IJ and R_IJK kernels; Fixed R_IJK (scheme: p_i=R_ijk*q_jk, BEWARE: antisymmetry and non_homogeneity strongly affect P2P and MatrixKernel, force not yet implemented); Improved consistency with potential theory for tensorial matrix kernels by defining number of phys vals NPV and number of potential vals NPOT (NRHS=NPV, NLHS=NPOT*NRHS).

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.

Introduced tensorial kernels for Uniform FMM (NB: Chebyshev UCB incompatible, TODO Chebyshev Sym), tested for kernel R_{,ij} and its derivative, fixed multidimensionnal fft, + some cleanup.

Change to kernel constructor prototype for Chebyshev and Uniform. Changes propagated to all Test and UTest files (I hope)

Implementation of Symmetric Uniform Kernel, optimized evaluation of derivative of Lagrange polynomials.

Implemented UniformGrid/Lagrange interpolation and factorized interpolation specific elements such as the MatrixKernel, Tensor and Mapping classes + Added required tests.
