Detailed Description
Reader for CBVS format.
The stream it works on will be deleted on destruction or if close() is explicitly called.
If you construct with glob_info_only == true, you cannot use the reader. After construction, the info() is then usable but no precise positioning is available. In other words, the trailer is not read.
From OpendTect v2.2.1, The toNext() interface will always return ascending inlines, no matter whether the data is stored with descending inlines.
