// Build Maker
// For making iOS and Android builds automatically at default paths outside project folder
// Default Path for iOS build is /Users/${UserName}/Documents/_Builds/${Product Name}/iOS Build
// Default Path for Android build is ${UserName}/Documents/_Builds/${Product Name}/Android Build
// Only active scenes in build settings are included in build
// No need to create any folders all folders will be created automatically
// If build already exists no need to delete, it will Append existing build for iOS
// If APK already exists with the same version it will be deleted and new build will be generated
// If build is completed succesfully respective folders are automatically opened
// Shortcut key for Generating iOS Build => Cmd + Shift + i
// Shortcut key opening Build Path       => Cmd + Shift + o
