Best way to reference ML model from another project? & Suggestion: new project type ML library

Question: What is the best way to reference ML model created by model builder in another project?
At the moment, I am copying the .zip files manually to all projects, but it is not a good way as number of models increase in the solution.

A feature like below could help in it.

**Is your feature request related to a problem? Please describe.**
Models may need to be shared between projects. At the moment, the project templates could not be referenced by other projects without taking care of manually copying the .zip file.

**Describe the solution you'd like**
There coulde be a third project type for "ML Library" on the Consume page

When referencing from another project, the zip file should be copied along to bin folder. Otherwise, .zip file is not found when running the prediction. If zip file is copied manually, then it also needs to be updated everytime on all projects referencing.
