view semiDefIneq.m @ 982:a0b3161e44f3 feature/getBoundaryOp

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add the following methods in LaplaceCurvilinear: getBoundaryOperator, getBoundaryQuadrature, getBoundaryBorrowing. Remove get_boundary_ops. Make interface and boundary_condition methods use the new methods.
