Fix IGC handling of invalid IGC files
Adding a JSDoc configuration for generating metadata on exported symbols

This generates info for all symbols annotated with "@todo api" (when Plovr is replaced, this will become "@api").  Generated metadata is written to stdout.  A separate process will handle the output.
Add a task to generate metadata on exported symbols

This runs JSDoc with the "symbols" config, providing a list of source files that have been changed since the previous run.  The output is used to generate a symbols.json metadata file containing all exportable symbols info.  A separate task will be run to generate the exports.js file.  These same metadata files will be used by a build tool.
Annotations for exports
Removing old *.exports for completeness
Write out sorted symbols, excluding inherited ones on private classes

There are cases where a private class may inherit an exportable member (e.g. ol.DebugTile_#getTileCoord comes from ol.Tile#getTileCoord).  We want to avoid making these exportable.
Allow main method to be called from elsewhere
Task for generating a limited set of exports
Use new generate-exports.js task
Regenerate symbols if parents have changed

The generate-symbols.js task runs JSDoc on source files.  Because this takes a long time (13s) to run on the whole library, the resulting symbols file includes additional metadata to make it possible to do incremental symbol generation on subsequent runs.  The 'path' and 'extends' metadata for a symbol are used to determine what needs to be regenerated.
Call generate-symbols.js from build.py
Unused script
Generate symbols before exports
Build task for driving the compiler
