Will need to implement the ambiguous parts next. Not clear yet that all of the ambiguous oracle steps should be discarded. Includes notes on the results of the top_down oracle
…mic oracle. Also, add a flag which turns on selective oracle transitions, and automatically ignore transitions after UNKNOWN unless --oracle_level is set Add an immediate close version of the close/open error. Add an immediate close version of the close/shift error. Add an alternate version of the close/shift and close/open resolutions - close at the end of the outer constituent Proposed fix of Open/Open: turn the new Open into a Unary Add a fix where open/open is closed at the end of the outer constituent Add a shift/open ambiguous fix - turn them into Unary Put the Close for a shift/open at the end, rather than earlier Includes stats for dev & test scores for various ambiguous transitions

Add an oracle for the TOP_DOWN transition scheme - seems to be effective in improving the scores for a top down parser
Includes unambiguous & ambiguous transitions
Also, keep track of stats for both the top_down and in_order oracles
