To add a new component to be seen as a Component node, add a new case to ComponentType enum, find its sourcekit equivalent in
strings /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/sourcekitd.framework/Versions/A/XPCServices/SourceKitService.xpc/Contents/MacOS/SourceKitService | grep source.lang.swift., and add the string as a new value to
the case key inside types dictionary in ScissorsExtensions.swift file.
Sometimes the tree obtained isn't same as the source code tree, so checking the AST dictionary is recommended first.
To add a new flag like -h or -v add a new class or struct and conform it to Flag protocol.
There are two types of options, InformationalOption and ExecutableOption. Informational option is used to
send information to Caprice public interface, while executable performs some changes on the resultant dictionary.
After adding the Option, add it as a case to optionObjectFromOption(_:_:) function inside OptionsProcessor class.
Add a new class that implements Rule protocol and add it as an element of the return array inside RulesFactory class.
Violation checking is performed by checkComponent(_:) function implemented by the protocol.
