Open a text requester to ask the user for a base pattern, then create a feature for each group of bases that matches that pattern. A new entry will be created to hold the features with the name "matches: <pattern>", where <pattern> is the pattern that was entered be the user. Any IUB base code can be used in the pattern, so for example, aanntt will match any six bases that start with "aa" and ends with "tt".
