 The method `getCurrentState()` returns the current status of SDK. Valid values are available via constant object `SDK.SDKState`:
 
-- `ACTIVE` SDK is connected to agent and capturing data.
-- `TEMPORARILY_INACTIVE` SDK is connected to agent, but capturing is disabled. In this state, SDK user can skip creating SDK transactions and save CPU time. SDK state should be checked regularly as it may change at every point of time.
