Removed sendSync as it provided no usefulness at this time; will consider adding an implementation back at a later time when it can be done correctly.
Updated documentation since sendSync was removed.
Revised stress testing strategy to use benchmark.js rather than the custom, repeating that was previously done.
Added stress tests for indexing, querying without wildcard and querying with wildcard. Querying is currently incredibly slow (to be expected).
Changed filename again; this aligns it more closely to how unit tests are separated.
