alogos's Issues

All examples in the document are not functioning properly ！！！

bnf_text = """
::= .
::= 0
::= 1
::= 2
::= 3
::= 4
::= 5
::= 6
::= 7
::= 8
::= 9
"""
grammar1 = al.Grammar(bnf_text= bnf_text)

When I run the above code, the following error prompt will appear：

alogos.exceptions.GrammarError: Following nonterminals appeared on a right-hand side of a production rule but on no left-hand side:

Random State Parameter

Hello,

Does the code support seed to define the random state?

I couldn't find it. It seems that every run I make generates a different result. This would be very important to replicate the same results later on.

Best,

Alex
