* Remove Protobuf dependency, add struct-ish class that mimics ABTExperimentPayload
* Remove a lot of the compiler errors, but not all of them. We need to figure out how RC serializes the NSData objects passed to FIRExperimentController in updateExperimentsWithServiceOrigin:
* Add ABTExperimentPayload class that replaces generated proto, refactor classes that depend on it
* Add unit testing class for ABTExperimentPayload
* Updates to ABTExperimentPayload API, tests for ABTConditionalUserPropertyTest, add tests for ABTExperimentPayload
* Update podspec to pull in testing resources
* Add utility class for parsing test files. Use it in ABTExperimentPayloadTests
* Fix FIRExperimentController tests
* Better documentation
* Run scripts/styles.sh
* Fix whitespace
* Remove protobuf imports
* Bump pod spec version for ABT SDK, depend on new ABT SDK in RC. Fix up RemoteConfigExperiment to use new ABTExperimentPayload object
* scripts/style.sh
* Update In-app messaging to use new ABTExperimentPayload class, which involves extending the ABTExperimentPayload initializer to accept different values for overflowPolicy and experimentStartTime
* Delete test payload
* Revert scripts/check_imports.swift
* Better initialization tags for ABTExperimentLite
* Update CHANGELOGs
* Remove private headers in podspec, use integerValue to parse integers
* Refactor ABTExperimentPayload header into Private headers. Fix integer types for millisecond metadata
* scripts/styles.sh
* Fix integer parsing
* Fix copyrights
* Fix CHANGELOG typo:
* Add private_header_files to public_header_files
* Try just using NSInteger for experimentStartTimeMillis
* Bump FIAM dependency on ABTesting
* Use long long for milli parameters (32-bit apps)
* Use longlong in test timestamps
* Don't cast to nsnumber in tests
* Use in64_t
* Fix Test Overflow
* Bump major version on ABT SDK
* Bump ABTesting version in Firebase.podspec
