Since we have a multithreaded dataloader (named `eachobsparallel` for the time being), we should also test in a multithreaded environment in github actions CI. related to #80

Lazy operations should be opt-in

Operation like `splitobs`, `shuffleobs` and many more return `ObsView`s that one has to call `getobs` on in order to materialize. I think this is unexpected for users coming from scikit-learn...

See comment [here](https://github.com/FluxML/Flux.jl/pull/1874#discussion_r807163671) and the related discussion cc @mcabbott

We should add gradient tests to functions that could be part of a trained model: - [x] `chunk` #47 - [ ] `unsqueeze` - [ ] `stack`, `unstack`

### TO PORT - [x] `labelmap`. Now `group_indices`. #10 - [x] `labelfreq`. Now `group_counts` - [ ] labelmap2vec - [ ] ind2label, label2ind, - [ ] labeltype, - [ ]...

Scope of this package

This package is kickstarting the plan outlined in https://github.com/JuliaML/LearnBase.jl/issues/49 - For the moment we can add both definitions and implementations here, at some point we will move the basic definition...

[WIP] drop julia < 0.5 and prepare for 0.6

trying to address #23

I did some perfomance tests for reading a file from a graph using my package FatGraphs; ```julia Pkg.clone("https://github.com/CarloLucibello/FatGraphs.jl") ``` For comparison I write a graph in a simple text format...

It should be added to the README

LazyModules is fine, but since this package is more specific, it is about loading packages, maybe a more appropriate name would be "LazyPkgs.jl" or "LazyPackages.jl". Saying this because if the...
