KoLite 1.0.1

Features include:
1) dirtyFlag (for change tracking)
2) activity indicator (ideal for commands)
3) command (with execute, canExecute, and activity features)


### asyncCommand
<button data-bind="command: loadCmd">Save</button>

saveCmd = ko.asyncCommand({
execute: function(complete) { ... }
})


### asyncCommand and Activity
<button data-bind="activity: saveCmd.isExecuting, command: saveCmd">Save</button>

saveCmd = ko.asyncCommand({
execute: function(complete) { ... },
canExecute: function(isExecuting) {
           return !isExecuting && self.isDirty()
       }
})

### dirtyFlag
// Your model
var Person = function () {
var self = this;
self.id = ko.observable();
self.firstName = ko.observable().extend({ required: true });
self.lastName = ko.observable().extend({ required: true });
self.dirtyFlag = new ko.DirtyFlag([self.firstName,self.lastName]);
return self;
};

Hook these into your viewmodel ...

//Did It Change?          
viewModel.dirtyFlag().isDirty();

//Resync Changes
viewModel.dirtyFlag().reset();
