GetData Library

Regarding the code, this is a minor bugfix release that adds missing but documented functionality relating to Dirfile Standards compliance, specifically the ability to use absolute paths in INCLUDE statements. It also fixes a few minor bugs discovered since the last release. This release also marks the introduction of support in GetData for Microsoft's Visual C++ compiler, but with a reduced feature set. Finally, a source package containing only the Interactive Data Language (IDL) bindings has also been produced, in cases where the library itself is already installed.
