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".
Create a new feature for each block of ambiguous bases. The new features will have a key of misc_feature and will created in a new entry called "ambiguous bases".
