Allow quoting symbols with apostrophe "'"

[marcofavorito]

Subject of the issue

Currently, in PL, the token SYMBOL_NAME (

pylogics/pylogics/parsers/pl.lark

Line 31 in 0c7626e

SYMBOL_NAME: /[a-z][a-z0-9_]*|"\w+"/

) is defined as follows:

SYMBOL_NAME: /[a-z][a-z0-9_]*|"\w+"/

However, this is a strict subset of the symbols acceptable by the standard at version v0.2.0. In particular:

• instead of "\w+", it should be "[^\"\n\t\r]"
• there should be another regex using ' as quoting symbol, i.e. '[^\'\n\t\r]'

Your environment

• pylogics: 0.1.0
