# ParameterHash is an intelligent Hash that allows you to add
# parameter values including the MIME extension paramaters that
# have the name*0="blah", name*1="bleh" keys, and will just return
# a single key called name="blahbleh" and do any required un-encoding
# to make that happen
# Parameters are defined in RFC2045, split keys are in RFC2231
