📄️ Config Sources
Adding a ConfigSource to the builder is the minimum step needed to build the Gestalt Library.
📄️ Config Tree
The config files are loaded and merged into a config tree. While loading into the config tree all node names and paths are converted to lower case and for environment variables we convert screaming snake case into dot notation. However, we do not convert other cases such as camel case into dot notation. So if your configs use a mix of dot notation and camel case, the nodes will not be merged. You can configure this conversion by providing your own Sentence Lexer in the GestaltBuilder. The config tree has a structure (sort of like json) where the root has one or more nodes or leafs. A node can have one or more nodes or leafs. A leaf can have a value but no further nodes or leafs. As we traverse the tree each node or leaf has a name and in combination it is called a path. A path can not have two leafs or both a node and a leaf at the same place. If this is detected Gestalt will throw an exception on loading with details on the path.

📄️ Config Loader
Each config loader understands how to load a specific type of config. Often this is associated with a specific ConfigSource. For example the EnvironmentVarsLoader only loads the EnvironmentConfigSource. However, some loaders expect a format of the config, but accept it from multiple sources. For example the PropertyLoader expects the typical java property file, but it can come from any source as long as it is an input stream. It may be the system properties, local file, github, or S3.
