------------------------------------
term                 -> select term
term1 > term2        -> select (child term1 term2)
term1 term2          -> select (descendent term1 term2)
term1 term2 + term3  -> select (sibling (descendent term1 term2) term3)

(descendent term1 term2) means:
  "select all matching term2's that are descendents of term1"
(sibling x y) means:
  "select all y's that are sibling's of anything that matches x"

need to build a tree grammar for selectors

-----more----
  1. implement additional properties
  2. dynamic application:
    - need a default stylesheet
    - applying a stylesheet should imply certain defaults.
      i.e. removing border declaration should actually imply
        no border if that's the default.
      likewise for background-color:  removing declaration should
      reset background-color to the default.
  3. background-color: a container's children should by default
      be transparent (i.e. not opaque) so that applying background-color
      on a container shows through properly / as expected.
