Subject: adding statistics about how many different kinds of expressions we have created in... 
X-Git-Tag: cvc5-1.0.0~8690
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=03a1f6a890027fa11cb0b00713757bc115debeb4;p=cvc5.git

adding statistics about how many different kinds of expressions we have created in the expression manager.
this is useful, for example, with --parse-only, to figure out a bit of problem structure
