This class represents the configuration of a CF engine. It is agnostic and doesn't contain any particular behavior for a specific engine.
Not all the data it stores applies to every engine though. The BaseConfig.cfc is not capable of reading or writing the config, it merely holds the data in a generic manner. If you want to read or write to/from a specific engine's format, you'll need to create one of the engine-specific subclasses, all of which extend BaseConfig.cfc.

Each of the components above supports these public methods:
setCFHomePath() - Points to the server home where the config files are to be read or written.
read( CFHomePath ) - Extract the config from the files found in the server home. You can override CFHomePath here too.
write( CFHomePath ) - Write the config out to the files in the server home whether or not they already exist. You can override CFHomePath here too.
getMemento() - Return all configuration in as a raw CFML data structure. Useful for passing config values to another instance.
setMemento() - Accept configuration as a raw CFML data structure. Useful for accepting another instance's data.
Create an instance of the component that corresponds to the server that you'd like to read or write config settings from, or the BaseConfig class if you want to deal with the generic JSON-based config.
