Initial setup of polar2grid.cris module
transplanted code from CSPP ql_cris_sdr. Need to find regex-based info routine equivalent
copied from cris_gtiff_rayg_201211 branch
transplanted cris2grid and bt_swath code
cleanups and futures
documentation comments
packaging
transplanted code from CSPP ql_cris_sdr. Need to find regex-based info routine equivalent
transplanted cris2grid and bt_swath code
cleanups and futures
fleshed out swath writer, still need missing value handling doublecheck and metadata dictionary generation
polar2grid.iasi templated off polar2grid.cris - need to add routines from metahoard.iasi.fbf
transferring from metahoard.iasi, which we intend to replace, improve upon and reduce dependencies
cleanups
better naming, polar2grid.{iasi,cris}.swath
This works in polar2grid.env on korra with eugene softlinked into site-packages:

iasi2fbf -L -o . /Users/rayg/Data/Iasi/IASI_xxx_1C_M02_20070806023857Z_20070806024152Z_N_O_20070806041434Z__20070806041907
addition of quality_flag, derived from GQisQualFlag
tested for iasi2fbf -L
fixed up single-detector export
moved iasi2fbf to its own module to make it easier to call with python -m
tested with/out -L and -d
approaching a beta iasi2fbf
more work, added polar2grid_drrtv
setup of setup for polar2grid.drrtv
