Add Literate tutorials with embedded tests

[rsenne]

Three tutorials in examples/ (basics, GLM emissions, ACDC model selection): Literate.jl scripts whose @test lines are hidden from the rendered docs with #src but run as part of the package test suite. docs/make.jl converts them into a Tutorials section, and test/runtests.jl includes each example as a testset.

Resolves #45
