bin/tnrs_db: documented how to estimate total runtime. note that our tnrs_db wrapper in inputs/.TNRS/tnrs/tnrs.make uses inputs/.TNRS/tnrs/logs/tnrs.make.log.sql as the log file.

inputs/.TNRS/schema.sql, data.sql: updated TNRS CSV columns to preserve Name_matched_accepted_family even though it isn't present in the current TNRS CSVs. this way, Name_matched_accepted_family can still be used for previously-scrubbed names, and family_matched can be added back to analytical_stem_view. (now that bin/tnrs_db uses an explicit columns list in COPY TO, the absence of a column in the CSV is no longer a problem.)

README.TXT: updating TNRS CSV columns: use the entire "COPY tnrs ..." statement instead of just the body of it so that the explicit columns list is included. this way, the COPY statement will cause an error if the TNRS schema was changed but inputs/.TNRS/data.sql was not yet updated.

bin/tnrs_db: removed unused imports

bin/tnrs_db: cumulative_tnrs_profiler: use tnrs.tnrs_request()'s new cumulative_profiler param instead of doing the profiling manually. this also ensures that there isn't extra time between when the cumulative profiler starts/stops and when the per-request profiler starts/stops (because Profiler's new add_subprofiler() method is used).

lib/tnrs.py: single_tnrs_request(): added support for a cumulative profiler using the cumulative_profiler kw param

lib/profiling.py: Profiler: added add_subprofiler(), for use with cumulative profilers

lib/profiling.py: Profiler: added add_time() and use it instead of `self.total +=`

bin/tnrs_db: tnrs_profiler: renamed to cumulative_tnrs_profiler to distinguish it from the tnrs_profiler used by tnrs.tnrs_request(), which just profiles the current request

bugfix: bin/tnrs_db: cumulative profiler: use len(names) instead of this_ct (cur.rowcount) in case the actual # rows fetched differed from the rowcount
