f7e4445358 Handle goto actions after reductions in a more standard way 
Rather than letting the reduced tree become the new lookahead symbol,
and re-adding it to the stack via a subsequent shift action, just
add it to the stack as part of the reduce action. This is more in
line with the way LR is described traditionally.

80ec303b10 Replace prec rule w/ left_assoc and right_assoc 
Consider shift/reduce conflicts to be compilation errors unless
they are resolved by a specified associativity.

647c3e2010 Add tests for editing all language examples

There are a few examples which still don't work and which have
been explicitly excluded, for now.
