Passing a context object to the task functions

[SamVerschueren]

In #17, the idea came up for passing a context object as argument of a task function. This would allow you to pass data from one task to another allowing you to create composable tasks.

Do we have to take something special into account when doing this? Because we are targetting Node 4+, are there any reasons why we should pass in a regular Object.create(null) object instead of Map?

Hi @SamVerschueren
any chances to see this merged soon? Would be awesome to use the output of a task in a successor task :)

Thanks for listr!

Will try to prioritize this. Thanks for the interest :).
