Parse table statistics.

[modulovalue]

Hello @mdaines,

I think it would be valuable to be able to see statistics on bottom up parse tables.

That is, a nondeterministic bottom up parser (LR(0)/SLR(1)/LALR(1)/LR(1)) has X amount of inadequate states, Y amount of shift reduce conflicts and Z amount of reduce reduce conflicts and I think it would be useful to be able to inspect X, Y and Z on the analysis overview page.

With this it would be possible to see if a stronger parsing theory was able to remove any conflicts or make inadequate states adequate.
