Visual feedback for RosettaScripts TaskOperations

TaskOperation elements in a RosettaScripts XML can be used to control the behavior of the packer at each residue, but it can be difficult to write these TaskOperation elements to produce desired behavior. Some TaskOperations behave non-intuitively, and it can be tough to follow the logic of ResidueSelectors.

It would be great if there were a button in the standalone to "Check TaskOperations," that could parse each TaskOperation in a RosettaScripts XML, and color which residues are designable (and to which residue types), which are restricted to repacking, and which cannot be repacked.
