Snippet Name: Count all words in a string

Description: This search pattern will match what is generally considered to be a "word". We consider that we have found a word each time a white-space character (specified in regex as s) followed by a non-white-space character (specified in regex as S) is matched. The very first word in a string will usually not match this pattern since it usually isn't preceded by a white-space character. To handle this special case we add an extra variation to the pattern. The carat ^ will match the beginning of the string that is searched.
