Inversify-express-utils release to match Readme?

[rcollette]

I was trying to follow the directions for using a Principal from the Readme of the inversify-express-utils and after struggling finally realized that the Readme is not in sync with the current release. Principal was made a generic back in March but there has not been a new package release. I was wondering when the next release of that package was going to occur.

My project is setup to not allow use of any and having a generic principal would fit the bill.
