Test for SWIG, build ERFA, and add spatial array index value comparison.

0.5.0-beta

Version bump to 0.5.0

External dependencies added to distribution

CUTE and ERFA have been added to the directory "external." Make will find CUTE, but building ERFA is currently not part of STARE's process. A number of minor modifications to README.me are included here, including one correction.

Build Improvements

Build improvements from OPeNDAP and UCSB are included. CUTE is now included in the distribution. This release rolls up all current pull requests.

ERRATA

• In the discussion of the Before/After bit in README.md, the correct statement should be non-positive years imply Before/After is zero.

Initial release candidate with new temporal API code

This release provides both spatial and temporal functions via the STARE API. Basic descriptions of the encoding are in the README. Both Boost and SWIG Python interfaces are available, with examples in contrib/python, which also demonstrate the low-level-lookup-tool. The main reason for this release is to provide basic spatiotemporal translation functions so that others may start to experiment going between lat-lon and temporal coordinates and STARE array index values. We expect the STARE API and index values produced are more stable than the version tag number suggests.
