Overriding default location of GodEye button

[headcrash13]

I've got a quick patch to be able to specify (override) the default location of the GodEye button:

GodEye/Classes/Configuration/Configuration.swift

Add:

open class Configuration: NSObject {
    open private(set) var command = CommandConfiguration()
    /// default switch configuration
    open private(set) var defaultSwitch = SwitchConfiguration()
    open var location:CGPoint? // Override default location of the GodEye button
}

GodEye/Classes/UIWindow+GodEye.swift

extension UIWindow {

    func makeEye(with configuration:Configuration) {
        GodEyeController.shared.configuration = configuration
                .
                .
                .

Replace:

        let rect = CGRect(x: self.frame.size.width - 48, y: self.frame.size.height - 160, width: 48, height: 48)

With:

        var rect = CGRect(x: self.frame.size.width - 48, y: self.frame.size.height - 160, width: 48, height: 48)

        if let location = configuration.location {
            rect.origin = location
        }

Usage:

       let configuration = Configuration()
        configuration.location = CGPoint(x: 40.0, y: 40.0)
        GodEye.makeEye(with: self.window!, configuration: configuration)

There are cleaner ways of doing this, of course (e.g. put defaults in header, then just overwrite the x: and y: values), but I wanted to be the least intrusive as possible. :)

Good job! GodEye button should be specify~
