# LicenseTemplateFinder
#
# Used to find license templates, which may come from a variety of external
# sources
#
# Params can be any of the following:
#   popular: boolean. When set to true, only "popular" licenses are shown. When
#            false, all licenses except popular ones are shown. When nil (the
#            default), *all* licenses will be shown.
#   name:    string. If set, return a single license matching that name (or nil)
