v0.0.4 Release

Summary

• Rename @opencensus/web-all to @opencensus/web-scripts so now this package
  is only in charge of bundling OC Web to allow importing it as <script> tag.

• To use OC Web as an npm dependency, there are several options: @opencensus/web-initial-load
  to instrument with only the initial page load module, @opencensus/web-instrumentation-zone
  to instrument it with all the OC Web functionality plus the Zone.js library and
  @opencensus/web-instrumentation-zone-peer-dep also exports all the functionality but Zone.js
  is a peer dependency.

• Implementation of User interaction tracing monkey-patching the Zone.js library. This includes
  some features like: automatic tracing for click events and route transitions, custom spans,
  automatic spans for HTTP requests and Browser performance data, relate user interaction traces
  back the the initial page load trace and sampling.
