Add tags to a set of comment lines in notes.txt

This opens a file called notes.txt in the current
working directory (creating the file if it does not
exist) and prepends lines to it containing the tags
that are passed in on the command line. Tags are
only added once. Can be run again any time to add

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called (Functional) Reactive Programming (FRP).

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

# Using the information available in the new iOS8 simulator for each 
# device/runtime (device.plist), this script creates a readable folder structure
# (no UDIDs, just simple device/runtime names). Inside that structure it creates
# soft links to your apps in development.
#
# You can run this script every time you install an app to your simulator, or
# you can simply call it to access this folder making sure it will always be
# updated :)
