"""
  Tool for querying the tests.

  Which tests to query?  Two options:
      1. Query only the tests that are run for a given configuration.
      2. Query all of the test files in the source directory
  For #1:
     Use dataDict as written out by gmakegentest.py in $PETSC_ARCH/$TESTBASE
  For #2:
     Walk the entire tree parsing the files as we go along using testparse.
     The tree walker is simpler than what is in gmakegentest.py

  The dataDict follows that generated by testparse.  gmakegentest.py does
  further manipulations of the dataDict to handle things like for loops
  so if using #2, those modifications are not included.

  Querying:
      The dataDict dictionary is then "inverted" to create a dictionary with the
      range of field values as keys and list test names as the values.  This
      allows fast searching
