* Avoid pruning paths with find
find . -path foo -path bar -path baz is horrifically inefficient;
properly excluding all of FirebaseAuth without excluding
Firestore/Source/Auth ends up taking 1.5 minutes on my machine.
Deleting via sed is much faster.
* Allow a branch name or filenames to be specified on the command line
e.g. ./scripts/style.sh master formats only files changed since master.
* Format Firebase/Source/Auth code
* Use alternate delimeter for path regexen
This simplifies the import process back into google3 and allows us to add additional directories to the project without needing to update the project files for each directory we add. This shows up most clearly in the change to Firestore/Example/Firestore.xcodeproj/project.pbxproj: this no longer needs to list essentially every directory in the project as a header search path.
* Clang-format configuration for C++ files
* Add support C++-only sources to the podspec
* Podspec support for fully qualified imports
* xcodeproj changes for fully-qualified imports
* Use fully-qualified imports in Firestore sources
