Added an Array extension with contains & indexOf -- bridging to NSArray is ugly and that hides it

ArrayUtils.swift

import Foundation

extension Array {
    func contains<U: Equatable>(object:U) -> Bool {
        return (self.indexOf(object) != nil);
    }
    
    func indexOf<U: Equatable>(object: U) -> Int? {
        for (idx, objectToCompare) in self.enumerate() {
            if let to = objectToCompare as? U {
                if object == to {
                    return idx
                }
            }
        }
        return nil
    }

    mutating func removeObject<U: Equatable>(object: U) {
        let index = self.indexOf(object)
        if(index != nil) {
            self.removeAtIndex(index!)
        }
    }
}

Outdated as of Beta 5 :(

yes, just uploaded a new version

IF you want to call that using a protocol .. e.g. MyProtocol, it won't work because you can't use a Protocol as a type constraint..

In that case I had to modify this to not use a generic but NSObjectProtocol
