Al	c67678087f	[parser] using a bipartite graph (indptr + indices) to represent postal code<=>admin relationships instead of a set of 64-bit ints. Requires |V(postal codes)| + |E| 32 bit ints instead of |E| 64 bit ints. Saves several hundred MB in file size and even more space in memory because of the hashtable overhead	2017-03-18 06:05:28 -04:00
