Updated methods in Feature Experimentation

Feature Experimentation has released two primary methods: `Decide``Decide` and `Track Event``Track Event`. All existing Full Stack Experimentation (Legacy)Full Stack Experimentation (Legacy) methods and implementation are still supported, but Optimizely Experimentation recommends updating to the new Feature Experimentation methods.

The new decide() methods eliminate the need to know when to use .activate(), .isFeatureEnabled() and other methods by combining the logic into one, easy-to-use .decide() method.

It is a non-breaking change that extends and builds on the existing functionality of isFeatureEnabled(), which is still a supported method for retrieving both legacy feature and new flag decisions.

Refer to your specific SDK's decide method reference documentation:

The new track event method tracks a conversion event (in other words, an action a user takes) for a user.

Refer to your specific SDK's track event method documentation:
