swift-format Default Settings

Since I've not found anywhere that describes the default settings of swift-format other than the code, I've pulled those settings out and presented them here.

Rules that are opt-in are marked as such.

Formating-Only Rules

(Most of these rules are defined in the default config, not the rules folder.)

1. maximumBlankLines = 1
2. lineLength = 100
3. tabWidth = 8

    // To find the needed buffer size you call sysctl with a nil results pointer.
    // This sets the size of the buffer needed in the bufferSize pointer.
