// Tips:
// [23:41:33] <@DHowett> theiostream: At the top of the function, get 'self.bounds' out into a local variable. each time you call it is a dynamic dispatch because the compiler cannot assume that it has no side-effects

// Global TODOs:
// IMPLEMENT PRETTY SOON: URL Request Caching better handling
// IMPLEMENT PRETTY SOON: Better handling of the fuckshit view controller view bounds thing
// IMPLEMENT PRETTY SOON [23:42:13] <@DHowett> theiostream: the attributed strings and their CTFrameshit should be cached whenver possible. do not create a new attributed string every time the rect is drawn
// IMPLEMENT PRETTY SOON: Push Notifications
// IMPLEMENT PRETTY SOON: Learn NSURLSession (iOS7+, but regardless... we can do two branches for certain moment and afterwards implement compatibility measures.

	So, since I'm about to implement the total/circle thing for the pie chart view (which is nice), I should write this up.
	Today, 4th of December 2013, I went to my school for the Pedagogic Day, where we were meant to discuss how parents
	and students could have a bigger part at school decisions.

	What happened:
	- Two days prior, Director Admir, who had been at our school for 28 years (my age * 2) was fired. Out of the blue. Due to mere "reorganization of the Diretoria".
        - This "reorganization" thing pretty much isolates Valinhos from São Paulo.
	- This day, two B-Zug teachers were fired for no reason at all.
	- After a promise this wouldn't be done until further discussion, wires for cameras are being installed in our classrooms.

	This is here to show how screwed-up our school direction is.
	Because it has become a corporation.
	Run by the four businessmen in suits who sit in a room in São Paulo: the Fundação Visconde de Porto Seguro.

	If I ever sell this app's codebase to them, I'd find it good that they actually see this.
	But that's not happening :P

// The whole -loadContentView API is not need-based. Rather, it is called on the controller's -loadView,
// and -unload is called on memory issues.
// That is, this is just a custom way to initialize and manipulate our main view, not really an
// awesome system to handle content views on-demand.
// Thought, might it be a good idea to implement this? We'd be splitting a view's management from
// our view controller's, but is that a bad thing if it spares us memory?
