Detailed Description

Base data table class, handles reading data files.

Base data table class--reads ASCII data files in various formats

1. Checks for the environment variable _envvar (defaults to "BABEL_DATADIR")

• Tries the _subdir directory if defined (def. "data") and then the main directory

1. Checks for the directory _dir (def. determined by the build environment)

• Tries the subdirectory corresponding to this version, then the main directory

1. Reverts to the compiled-in default data
