Create `Naming`-variations on-the-fly

[sebastian-peter]

In Naming.java, all variants of a provided String are calculated during construction of the object.

Lines 33 to 50 in c752e38

	String flatCase = String.join("", components);
	String upperFlatCase =
	components.stream().map(String::toUpperCase).collect(Collectors.joining(""));
	String camelCase = String.join("", camelCasing(components));
	String pascalCase =
	components.stream().map(StringUtils::capitalize).collect(Collectors.joining(""));
	String snakeCase = String.join("_", components);
	String screamingSnakeCase =
	components.stream().map(String::toUpperCase).collect(Collectors.joining("_"));
	String camelSnakeCase = String.join("_", camelCasing(components));
	String pascalSnakeCase =
	components.stream().map(StringUtils::capitalize).collect(Collectors.joining("_"));
	String kebabCase = String.join("-", components);
	String donerCase = String.join("|", components);
	String screamingKebabCase =
	components.stream().map(String::toUpperCase).collect(Collectors.joining("-"));
	String trainCase =
	components.stream().map(StringUtils::capitalize).collect(Collectors.joining("-"));

This is rather time and space consuming, as in most cases, only a small number is actually required. The code could be adapted to construct the desired variant on-the-fly when any method such as flatCase() is called. One could even implement some sort of caching here, where the variants are only lazily built once they're requested.
