Alessandro Coglio 64307d075c [ABNF] Add new operators. 
This adds shift (`<<` `>>`) and bitwise logical (`&` `|` `^`) operators.

Their precedence is between the additive and ordering operations, in this order
(higher to lower):
- ... others, to additive
- `<<` and `>>`
- `&`
- `|`
- `^`
- ... others, from ordering

This is consistent with Rust, but not with C and Java, both of which make the
bitwise logical operators lower-precedence than equalities.

The previous ABNF rule names for `conjunctive-expression` and
`disjunctive-expression` have been renamed to be more consistent with the newly
added ones. Also, the rule names "abbreviate" 'conjunctive' and 'disjunctive'
with 'and' and 'or', otherwise the names were a bit too long.

# ABNF Grammar

This directory contains both the ABNF grammar for the Leo language and a Rust binary to help convert the ABNF grammar file to a markdown file.
