<DD>A constant for getPriority() used for Trivial validation checks.

 This is a Priority Hint to Validation Processor based on computational
 expense.

 Trivial is used for thing that don't require any real work - like
 checking for any O(1) opperations such as checking null values.

 <p>
 This is a Priority Hint to Validation Processor based on computational

 Used for simple attribute or geometry validations, basically anything
 that is Order(N) like a Bounds check.

 This is a Priority Hint to Validation Processor based on computational

 <p>
 Used for complex validations, basically anything that is has a Chance of
 being worse then O(N).

 <p>
 Any integrity tests between two FeatureTypes should be an example of a
 PRIORITY_COMPLEX.

 This is a Priority Hint to Validation Processor based on computational
 expense.
 </p>
 
 <p>
 Used for involved validations, basically anything that is has a Chance
 of being worse then O(N^2).

 <p>
 Any integrity tests involving network code, were we have to build the
 network and then walk it, is an example of PRIORITY_INVOLVED.
