How to find the value for a given key, in a particular file. The notion of "key" and "value" are a bit loose. See the documentation.
# In this example, we demonstrate how to find the value for a given key, in a particular file,
# using the Bash Shell Scripting language. We've setup some primitive functions to provide
# some modularity. See near the end for example usage on how you might call this.
# Assumptions:
# 1. Stripping leading and trailing whitespace in the value string is desired.
# 2. The last occurrence of the key (if there are multiple) is all we care about.

idStar / AppDelegate.m
Created Sep 13, 2014
A way to exit full app launch mechanics when you're simply invoking the XCTest target and want to speed things up.
View AppDelegate.m
#pragma mark - XCTest Support
static BOOL isRunningTests(void) __attribute__((const));
We need a mechanism to detect if we have been invoked / are running from a unit test.
If we are, we'll want to exit early instead of doing all kinds of view controller setup.
This function determines based on the environment, if we're running in a unit test process,
such as XCTest.

#pragma mark - Reachability
* This kicks off a check for our website's reachability in the context of needing it to display, or alert the user
* of error, just once. That's why we stop the notifier in both reachable and unreachable callback block handlers.
* We're not looking for ongoing callbacks through the life of the application; we just want to know the one time.
* This is meant for an iPhone app only, hence, no explicit WWAN setting.
