Drops the inline callouts from the painless reference book. These
callouts are incompatible with Asciidoctor and we'd very much like to
switch to Asciidoctor for building this book, partially because
Asciidoctor is actively developed and AsciiDoc is not, and partially
because it builds the book three times faster.
This updates the casting table to reflect the recent changes for casting consistency in Painless. This also adds a small section on explicitly casting a character to a String which has always been allowed but undocumented.
Full restructure of the spec into new sections for operators, statements, scripts, functions, lambdas, and regexes. Split of operators into 6 sections, a table, reference, array, numeric, boolean, and general. Clean up of all operators sections. Sporadic clean up else where.
