Remember that it is a library for you to serve in tests and as an introduction to this topic and debug. It should not be used in production for final projects until the final version that I hope is complete throughout this month of December is published and will also contain creation and use of google documents (sheets, doc and slides, and other surprises) .
Also, there may be changes in the names of the methods or datas of some classes.
Please send me your suggestions and found problems.
