v1.0.0

• Initial Release--for Google-use only. This library is the foundation of a network transport layer that focuses on transparently and respectfully transporting data that is collected for purposes that vary depending on the adopting SDK. Primarily, we seek to reduce Firebase's impact on binary size, mobile data consumption, and battery use for end users by aggregating collected data and transporting it under ideal conditions. Users should expect to see an increase in the number of Cocoapods/frameworks/libraries, but a decrease in binary size over time as our codebase becomes more modularized.
