/** 
  * This script bundles d.ts files generated by typescript compiler and your own d.ts files.
  * The reason for the need of copying your own d.ts is that tsc won't generate typings for files with only types/interfaces,
  * hence they won't end up in the declaration folder. 
  *
  * Specify typings in package.json
  * "types": "dist/index.d.ts"
  *
  * Set the following props in tsconfig.json under "compilerOptions":
  * "declaration": true,

// We've been working for a full day hunting down why AngularJS 1.5 retains large data sets after a component is removed.
// We don't know the exact cause, since there are many parts involved. 
// But jQuery cache, $scope.$$watchers, $transclude all seems to be different players in this issue.
// We provided a super large data (used about 1GB+ of memory) to a sub component in our template. 
// But when resetting the component to apply new data instead of using the same amount, 
// the memory doubled until the new component was rendered and Angular eventually cleared the scoped.
// Since this ended up using almost 3GB it crashed Chrome for our users.
// After testing everything trying to clean our objects it was still an issue since the data was references in so many places by Angular.
// Our solution was to thoroughly clean all child scopes for our destroyed component by deleting all watchers, all non-angular props,
// and if those props where objects, also delete those sub props in case other references to t
