/*#
@method get ConfParser
@brief Retreives the value associated with a key.
@param key The key of which the value is to be read.
@optparam section If provided, the section where the key is found.
@return The value (or values) of associated to the key, or nil if not found.
The method retrieves the value associated with a given key. If section parameter
is not provided, or if it's nil, the key is searched in the main section, else
it is searched in the given section.
If the section does not exist, or if the key is not present in the given
section, the method returns nil. If the key exist but has no value associated
with it, an empty string is returned. If there is only one instance of the key,
a single string containing the value is returned. If multiple entries for the
given key are found, all the values are returned as strings in an array.
The caller should verify the if the returned value is a string or an array using
typeOf() function. Alternatively, it is possible to use @a ConfParser.getOne to be sure to
retrieve only strings.
Categorized keys can be retrieved with this method by providing their full name.
