The tagging code hooks \@startsection to emit the H1/H2/H3 tags that a
screen reader navigates by. titlesec replaces \section wholesale rather
than going through that hook, so every heading vanished from the
structure tree --- with no error to say so, which is why this went
unnoticed. titling separately left an unclosed trivlist behind its
\flushleft declarations, producing "the number of automatic begin and
end text-unit para hooks differ" and a mis-nested tree.
Both files now style headings through \@startsection and the title
block through \@maketitle, using the class's own hooks. The style
argument of \@startsection is applied to the whole heading, so the
memo's uppercase headings append \MakeUppercase to it; the tagging code
wraps the section number in \NoCaseChange so the number is left alone.
Vertical spacing was matched against the previous output page by page:
the memo now renders identically bar one heading a pixel off, and the
paper's title block lands within two pixels.
datetime is dropped from cdsc-paper.sty. Only \today was ever used from
it and that is built in.

This is an article-class equivalent of the cdsc-article chapterstyle
from cdsc-memoir.sty, written so the paper template can drop memoir
(which is incompatible with the LaTeX tagging-project) while keeping
the same look and feel.
Uses titlesec for section heads, titling for the title block,
fancyhdr for the page styles, enumitem for tighter list spacing,
and caption for the caption font. The runin abstract and \\published
note hooks behave the same as before.
