go into directory containing a file or dir matching a pattern

cdd-cdf.sh

# go directly into a directory containing a file or directory with a matching pattern.
# use cdf to match a file, use cdd to match a dir
# e.g. 
# cdd mydir # will match files of the type .*myfile.*
# cdd myd.subd # will match like .*myd.*subd.*
# cdd myd.subd$ # will match like .*myd.*subd$
# cdf myfile # will match files of the type .*myfile.*
# cdf myfile.txt$ # will match files of the type .*myfile.txt$
