<High Priprity>
* enable ALIAS inside LOCAL
* there are no ways to initialize settings in GLOBAL (when reloading xml)
* parasite deeply on vmd
* make enable to inherit color spcified in vmd
  (only ColorID specification. Others maybe much more difficult.)
  Currently(0.321), only secondary structures can inherit some colors
  specified by ColorID. (colors such as orange2 and cyan2 cannot be inheritted)
* MO iso-surface smoothing (shader etc.)
* There must be a problem concerning setDepthTest, setCulling, and shaders.

<Medium Priority>
** stepwise reading (partially implemented, though)

<Just a plan>
*** display object name when clicked (tedious and speed may be sacrificed)
*** OpenFL and WebGL
*** builder: xyz format (babel is enough?)
*** retrieve pdb file directly from PDB (flash security is the only problem)
