Use as package dependency

[iskiselev]

I'm working on package that needs to transform some user files.
The only thing that I need from SlowCheetah in that case is to provide SlowCheetah.TransformTask that I will execute from my package. I'm not feeling safe enough to just reference SlowCheetah, as it will integrate other tasks in build pipeline - that may result in transforming of some user files. Can smaller package be released that will be good to used as dependency, that will not add any custom logic in msbuild except of defining task with UsingTask?
