Book Erratum Rx.Net v6.0

[jfferland]

Hi,

I read the new version of Rx.Net v6.0 and it was great to understand deeply the concept behind Rx.

I noted a few light mistakes and I think it can be corrected quickly :

1. page 235 - AppendixD:Rx’sAlgebraicUnderpinnings - code example
   this.downstreamSubscriber.OnCompleted(x); -> this.downstreamSubscriber.OnError(x)

2. page 235 - AppendixD:Rx’sAlgebraicUnderpinnings - missing word
   These theoretical ideas and concept? were incorporated into the Haskell programming language

3. page 238 - Monadic law 2: Return is a ‘left-identity’ for SelectMany
   change left-identity for right-identity

Thank you again for the great quality book!
