# Description

Earlier the `TerrainGeneratorCfg` and `TerrainImporterCfg` were in the
same file. However, this leads to some issues with circular dependencies
when referring to the `TerrainImporter` as an attribute of the
`TerrainImporterCfg` (i.e. providing the class name as a member of the
config object).

The MR fixes the above circular dependency. Also, it moves all the
terrain parameters to its configuration object to make the terrain
initialization consistent with the other asset constructors.
