Description:
convert flat hash to nested data using TT2's dot convention
Converts a CGI query into structured data using a dotted name convention similar to TT2. expand_cgi works with CGI.pm, Apache::Request or anything with an appropriate "param" method. Or you can use expand_hash directly. . If you prefer to use a different flattening convention then CGI::Expand can be subclassed.
