Fixed a bug in test.d
Fixed another bug
Made multidim_rfft work for onedimensional transforms.
Debugged *all* the things.
Re enabled gcc attributes.
Changing direct API for real multidim.
Added multidim support to pfft.pfft.Rfft.
Changing capi to support real multidim.
Changed the C API to multidim.
Added separate Twiddle type and implemented MultiScalar template.
Making FFT work with MultiScalar.
Added tests for multi-scalar.
Changing multidim implementation to use multi-scalar where possible.
Use vector single transforms instead of scalar ones for transposed fourier transforms where the number of transforms is too small to use multi-scalar.
Moved some code from pfft.clib to pfft.common_templates.
