Detailed Description

Describes all the information in an sarray index file. The index_file_information struct contains all the information assocaited with a single sarray column. In a version 1 SArray, the index file describes a single column. As such index_file will point to the actual file location. In a version 2 SArray, the index file describes multiple columns. As such, index_file is of the form [file_location]:[column_number], and column_number may be non-zero. Column numbers are 0 indexed. segment_files are similar. In the v1 format, the segment_files point to the actual files. In the v2 format, the segment files are of the form [file_location]:[column_number].
