# Use what type of error indicator?
# exact => comparison with analytic solution
# kelly => inter-element normal derivative jumps
# patch => patch gradient recovery
# uniform => uniform refinement

# Mesh refinement type: h, p, matchedhp, or hp
# Use HIERARCHIC or HERMITE functions with p/matchedhp/hp,
# Use an exact indicator with matchedhp/hp.
# matchedhp refinement stupidly does both h and p or neither
# on every element; hp refinement tries to do one or the other

# We generate 1D meshes on [-1, 0].
# We load lshaped.xda for 2 dimensional problems, lshaped3D.xda for 3

# Element type - tensor or simplex
