Added integration methods QAWS, QAWO, QAWF; new tests for numerical integration
Integration methods integration-QAWS: adaptive integration for singular functions integration-QAWO: adaptive integration for oscillatory functions integration-QAWF: adaptive integration for Fourier integrals have been added in a file numerical-integration-with-tables.lisp. These require tables with are new mobjects. All of the tests from GSL in gsl-1.11/integration/test.c and gsl-1.11/integration/tests.c for ported functions are now in either this file or numerical-integration.lisp. SBCL 64: TOTAL: 1522 assertions passed, 5 failed, 0 execution errors. CCL 64: TOTAL: 1525 assertions passed, 2 failed, 0 execution errors.
