Validates (sort of) and formats a bibcode id.
Format for bibcodes is specified here: http://adsabs.harvard.edu/abs_doc/help_pages/data.html#bibcodes
But, this: 2015arXiv151206696F is apparently valid so apparently, the only things that really matter are length, 19 characters
and first four digits must be a year.  This function makes these tests:
length must be 19 characters
characters in position
1–4 must be digits and must represent a year in the range of 1000 – next year
5 must be a letter
6–8 must be letter, ampersand, or dot (ampersand cannot directly precede a dot; &.
9 must be letter or dot
10–18 must be letter, digit, or dot
19 must be a letter or dot
]]
