This is a reusable angular directive that provide support for multiline ellipsis It is based on the isea presented at https://www.mobify.com/blog/multiline-ellipsis-in-pure-css/
Note: this implementation assumes that the content wraps and uses height to determine overflow situation. In cases where content gets truncated due to its width, this implementation is not good enough.
