the dbf file is big

[DeoLeung]

I save two million point to shp files using Fiona and pyshp, it's impress that pyshp is much faster, thx for the great library, but I'm confused about the dbf file, the output from Fiona is about 18m while pyshp is 93m, any hints about this?

I think the bigger size comes from the field size, maybe we could defined some non-dbf constants , like INT=11, BIGINT=20, to reduce complexity for newbies like me
