/**
* The public method to start the encoding
* This method takes an array of config values and applies some standard rules for formatting on it
*
* Beware that the applied rules follow some basic formatting principles for node.config.php
* and doesn't support any custom formatting rules.
*
* f.e. associative array and list formatting are very complex with newlines and indentations, thus there are
* three hardcoded types of formatting for them.
*
* a negative example, what's NOT working:
* key => [ value1, [inner_value1, inner_value2], value2]
* Since this isn't necessary for config values, there's no further logic handling such complex-list-in-list scenarios
