Unable to access WebOptimizer.Processors

[Ard-Emanon]

As per nuget version 3.0.405 I should be able to access WebOptimizer.Processors, as to set GenerateSourceMap to true. However, I'm unable to do so for some reason. I'm unsure if this is a mistake on my part, a conflict with codeessentials.WebOptimizer.Dotless (v3.1.0) or something else.
