=begin

Scans java test source files, recursively from the current directory,
and produces a list of test metods sorted by specification line number.

The implementation makes heavy use of my scant knowledge of regex.  I'll
comeback and clean this up as time allows.

Assumes a test comment convention like this:

    /**
     * Lines 410,411,412,413:
     * <p>
     * A method of a conversational interface may be marked with an
     * "@EndsConversation" annotation. Once a method marked with
     * "@EndsConversation" has been called, the conversation between client and
     * service provider is at an end, which implies no further methods may be
     * called on that service within the *same* conversation.
     */
    @Test
    public void atEndsConversation1() throws Exception {

Example command line usage
>ruby processcomments.rb > comment_scan.txt

Current output is formatted for a cwiki page and can be directly pasted to a blank page

Some TODO's:
  Add logic to process number ranges such as "Lines 523-556" or "Lines 523 to 556"
