// .NET JSON Date decoder
// ---------------------
// This filter takes a .NET JSON encoded date and makes it readable...
// i.e.  /Date(-795988800000-0400)/ turns into 10/11/1944
// to use in your template just do.... {{ mydata.somedate | jsonDate }}
// If moment.js is included in your project, you can pass an optional
// second parameter "format" with a moment.js-compatible date format string.
// If the second parameter is empty or moment is not included, we'll fall back to default.
