Release 0.2alpha

Substantially-refactored release, with much simpler usage (often just a method chain). Includes filtering by column and row and aggregating.

Release v0.1alpha

First release of libhxl-js -- supports basic hashtag parsing, but not (yet) compact disaggregated syntax. This first version of the library already expects the raw HXL to be loaded into an array of arrays, equivalent to the raw CSV; future versions will include code for loading online CSV files directly via URL.
