ReplaceSequence

Wraps the usage of making multiple string replacements in an ordered sequence. For Example... instead of doing this over and over:

    String text = "   Some example text     ";
    text = text.` String#replaceAll(String, String) replaceAll`("e", "E");
    text = text.` String#replaceAll(String, String) replaceAll`(" ", "_");
    text = text.` String#replaceAll(String, String) replaceAll`("^\\s+$", "");

You can use a ReplaceSequence like this:

    static final betterReplacements = ReplaceSequence.` #create(String, String) create`("e", "E").` #append(String, String) append`(" ", "_").` #append(String) append`("^\\s+$");

    void fixMyString(String text) {
      return betterReplacements.` #replaceAll(String) replaceAll`(text);
    }

Internally, an ordered list of Matchers and its associated replacement is built as the #append method is called.
Each matcher is Matcher#reset(CharSequence) reset with the input specified in the #replaceAll(String) method. Use of this class can improve performance if the sequence of replacements is intended to be used repeatedly throughout the life of an application.
This is due to the fact that each Pattern is only compiled once and each Matcher is only generated once.
