/*
 * Note: You need to build this script before use
 * Usage:
 *       1. Build by `swfitc scan_unused_selectors.swift`
 *       2. Run by `./scan_unused_selectors /path/to/yourMachO`
 * 
 * How to locate MachO of your APP (`/path/to/yourMachO` in above example)? In your Xcod project navigator, you can find a folder `Products`
 * In that folder you can see your app (after any build) and right click on it -> "Show In Finder"
 * You can get your APP's location by drag it into your terminal. Say it's "/path/to/MyApp.app", your MachO path would be "/path/to/MyApp.app/MyApp"

// How to apply color formatting to your log statements:
// 
// To set the foreground color:
// Insert the ESCAPE_SEQ into your string, followed by "fg124,12,255;" where r=124, g=12, b=255.
// 
// To set the background color:
// Insert the ESCAPE_SEQ into your string, followed by "bg12,24,36;" where r=12, g=24, b=36.
// 
// To reset the foreground color (to default value):
// Insert the ESCAPE_SEQ into your string, followed by "fg;"
