## Detailed Description

Basic metadata information about a GeoTessModel.

GeoTessMetaData stores basic information about a GeoTessModel, including:

- Description of the model.
- The names of the layers that comprise the model.
- Map from layer index to grid tessellation index.
- The names of the attributes supported by the model.
- The units of the attributes
- The DataType of the attributes (DOUBLE, FLOAT, LONG_INT, INT, SHORT, BYTE).
- The name and version number of the software that generated the model.
- The date that the model was generated.
- The computer platform upon which the code was compiled.
- The name of the file from which the model was loaded.
- The amount of time required to load the model from file.

Each GeoTessModel has a single instance of MetaData that it passes around to wherever the information is needed.
