Log for options.go

• Use float64 directly for the compression option by Caio 5 years ago
• Tidy things up [gometalinter] by Caio 7 years ago
• Expose options to change the RNG being used 💬 by Caio 7 years ago

  This patch creates a new public interface `TDigestRNG`
  and exposes two new options:
  
  - tdigest.RandomNumberGenerator(TDigestRNG)
  - tdigest.LocalRandomNumberGenerator(seed)
  

• Make New() return an error instead of panic()ing 💬 by Caio 7 years ago

  This patch now makes New() return a (*TDigest,error) tuple,
  which makes deserialization safe without having to trap
  for panic()s.
  
  The only remaining panic() is for bad input in a public
  function (`Quantile(float64)`). I'm keen on keeping it.
  

• Introduce a parameter-less New() 💬 by Caio 7 years ago

  Now `tdigest.New()` gives a sane ready-to-use-in-most-cases digest.
  
  Configuration should be done via self referential functions. Ex:
  
      // create a digest with compression of 200
      tdigest.New(tdigest.Compression(200))
  
  Notice that New() can still panic, which means that deserialization
  if still more dangerous than it should.
