Recursion can be used.

We're reading from disk, so we go from type in disk to type in destination
The type of destination is SomeVectorType
The underlying type of destination is SomeVectorType::value_type
Therefore, we have underlying type in disk and underlying type in destination
Let's call floating the set {double, float}
underlying type ut_disk in disk is in {floating, complex, other}
underlying type ut_dest in destination is also in {floating, complex, other}
if ut_disk == ut_dest all is good
if ut_disk != ut_dest we throw unless
ut_disk == floating and ut_dest is std::complex<floating> so
that we can go from floating to complex<floating>

I won't talk too much about implementation because it might change.
Note the complication of taking Real<SomeVectorType::value_type>::Type
which is not discussed here because
"The source is fully true." (Gonzalo, 2021)

As far as disk is concerned, a name + "ComplexOrRealType" single char set
is written to the hd5 file only if
vector<floating>, with content 'R'
vector<std::complex<floating> >, with content 'C'
all other vectors aren't prepended at all and
a read for name + "ComplexOrRealType" set in the hd5 file will fail.

writing std::vector<std::complex<T> > in IoNgSerializer
now writes a marker before, with name equal to
name of vector + "ComplexOrReal" and content "C"
This marker isn't written if the vector is real.
readInternal tries to read the marker allowing
reads from real --> complex, in addition to the
real --> real, and complex --> complex.

If the file PsimagLite/src/Ainur/Config.make
doesn't exist then configure.pl
creates it by copying into it
PsimagLite/src/Ainur/Config.make.sample
This last file has been updated for
correct compilation of Ainur's examples.

These preprocessor flags, when enabled,
make int long be the type used in
PsimagLite BLAS and LAPACK headers
respectively as opposed to just int
