Re: Next release, sample API

[Jeff Tranter]

I have doxygen comments ready to commit. I have just a few questions:

- are the samples written using csl_sample_write in a fixed format or are
  they inferred from the name?

- can you call csl_sample_write more than once, and if so, are the
  samples concantenated together?

- ssl_sample_cache_add was not implemented. I added an empty
  function definition in cslsample.c so I could document it.

- will the behaviour (e.g. caching) be the same when using the OSS
  backend as compared to the aRts backend?
