Implied and now executed tasks:

• downstream testing (so core would know it didn't break deps, etc)
• delegate tests down to living next to relevant code
• delegate demos down to living next to relevant code

The releasing of all the non-fundamental modules as independent CPAN has been completed. Still to do:

• making the PCHIP funcs be kernels, not separate C file
• fix the type-conversion gremlin revealed in FFTW3 work

After releasing 2.096:

• PDL::Slatec:
  • remove PCHIP stuff from (the EISPACK stuff in there, rs (symmetric), is different from (though unlikely to be much better) the port of rg (general) in MatrixOps/eigen.c - I got confused by eigens.c, but that's from SSLib, not EISPACK)
  • say it's deprecated in favour of PDL::LinearAlgebra
• update Proj4 and GSL with lib/*.pd stuff
• update TriD with code-yoink
• update FFTW3 to exploit fixed type_coerce
