Significant modif in Chebyshev FMM (may impact your library): Provide a variant of ChebM2L without compression (new name FCheb) and use prefix FChebCmp for the compressed variant (former FCheb); Now FChebTensorial does exactly the same thing as FCheb but for tensorial kernel matrices.

Major modification! Defined rigoreous targetsource convention: p(x)=sum_y K(x,y)w(y) with x=target and y=source. Direct computation is done by calling MutualParticles(Target params,Source params) or P2P(Target, Source); Kernel matrices evaluation is done by calling evaluate(x=target,y=source) which returns k(x,y)=k(xy).

Some more cleanup in MatrixKernel class (renaming DIM to NCMP, to avoid confusion in other applications) as well as in Chebyshev/Uniform Tensorial tests.

BLANCHARD Pierre authored
Redesigned direct DFT and FFT classes (provided a separate complex valued FFT and templatized direct DFT with physical value type); Provided test for Cinterfaced Lapack functions such as Cholesky Decomposition (TODO add SVD and QRD).

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).

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

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).
