* Replace Cactus complex number type with C/C++ complex numberseschnett2013-03-08
| | | | | | | | | | | | | | | | Map CCTK_COMPLEX to "double complex" in C, and "complex<double>" in C++. (It is already mapped to "double complex" in Fortran.) Update type definitions. Re-implement Cactus complex number math functions by calling the respective C functions. Update thorn that access real and imaginary parts of complex numbers to use standard-conforming methods instead. git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/LocalInterp/trunk@216 df1f8a13-aa1d-4dd4-9681-27ded5b42416
