FnService - Function Service
FnService is an Angular Factory in the Util module with the name fn.js
. It provides general purpose functions that are useful throughout the client-side application. To use these functions, see the documentation on injecting Angular services.
Note: some of these functions are repeats of jQuery functions. Since we are not using jQuery, we wrote our own implementations.
