Deletion of Newton da Costa

Comment: With an h-index of 38 according to Google Scholar, a very clear pass of #1 in a field (mathematical logic) that does not generally have high citation rates. The article itself either needs pruning or far better sourcing - it is probably generally accurate, as the topics discussed match the subject's most highly-cited papers, but while the citation rates establish the subject's notability, we still need verification for individual claims
