I spent many hours today working on capture.ew  its almost done. I should be
able to post it to rapideuphoria.com  before monday.
let to be done: code cleanup and testing

features:
- 100% euphoria code
- can capture child process stdin (main process can pipe output to its child
handle 0)
- can capture child process stdout (main process capture child console output
sent to hamdle 1)
- can capture child process stderr (main process capture child error messages
sent to handle 2)
- can capture any combination of 3 above.
- very simple interface
-   capture_exec(cmd_line,option)
-   capture_gets(handle)
-   capture_puts(handle, object data)
-   capture_terminate()
