Returns the currently cached color for a ClangToken, or takes the next color
from the color palette and assigns it to this token.
<p>
NOTE: token is assumed to not be null 
NOTE 2: this highlights individual variables NOT labels on taint; that should be something we need to do.

@param token - the token we wish to highlight.
@return the color currently assigned to this specific token.
