Tarantol SQL grammar online editor/tester

[mingodad]

I've just added tarantool/src/box/sql/parse.y to https://mingodad.github.io/parsertl-playground/playground/ an Yacc/Lex compatible online editor/tester (select Tarantol SQL parser (partially working) from Examples then click Parse to see a parser tree for the content in Input source editor).

I hope it can help debug/develop/test/document this project SQL grammar.

Comparing it with SQLite3 (also there) I've noticed that sqlite3 accepts BEGIN or BEGIN TRANSACTION to start a transaction but tarantol only START TRANSACTION (no shortcut).

Any feedback is welcome !
