**        The EcwCompressionTask is used to simply do compressions.

**

**        Usage is:

**                ecw_compress_task_new()                        - to create one of these structures

**                ecw_compress_task_parse_args()        - (optional step) parse command line args into task structure

**                ecw_compress_task_setup()                - will open input, and compute size details

**                ecw_compress_task_compress()        - do the actional compression. Skip this step to just get file sizes

**                ecw_compress_task_delete()                - to close the structure and any associated data
