-- fixing parser to handle simple cases like
user=>  (zc/css [[:html]])
"\n\nhtml"

user=> (zc/css [[:html [:body]]])
"\n\nhtml\n\nhtml body"

user=> (zc/css [[:html [:body {:foo "bar"}]]])
"\n\nhtml\n\nhtml body{ \n  foo : bar; }"
-- adding test cases for these simple inputs

user=>  (zc/css [[:html]])
"\n\nhtml"

user=> (zc/css [[:html [:body]]])
"\n\nhtml\n\nhtml body"

user=> (zc/css [[:html [:body {:foo "bar"}]]])
