2021-04-08	Rename volume-experiment to volume-importance.	Arun Isaac
	* src/extent-sampling.sc, include/extent-sampling.h (volume-experiment): Rename to volume-importance.
2021-03-16	Deal in solid angle fractions, not absolute solid angles.	Arun Isaac
	* src/extent-sampling.sc (volume-cone): Use solid-angle-fraction->planar-angle instead of solid-angle->planar-angle. * src/nd-random.sc (planar-angle->solid-angle): Rename to planar-angle->solid-angle-fraction and return a solid angle fraction. (solid-angle->planar-angle): Rename to solid-angle-fraction->planar-angle and accept a solid angle fraction. (hollow-cone-random-vector): Use planar-angle->solid-angle-fraction instead of planar-angle->solid-angle. (beta-inc-unnormalized, incomplete-wallis-integral): Delete functions. * include/nd-random.h (planar_angle_to_solid_angle): Rename to planar_angle_to_solid_angle_fraction. (solid_angle_to_planar_angle): Rename to solid_angle_fraction_to_planar_angle. * scm/nsmc/wrap.scm (planar-angle->solid-angle): Rename to planar-angle->solid-angle-fraction.
2021-02-26	Add copyright and license headers for all files.	Arun Isaac
	* include/extent-sampling.h, include/gaussian-nd-random.h, include/integrands.h, include/nd-random.h, include/oracles.h, include/utils.h, src/extent-sampling.sc, src/gaussian-nd-random.sc, src/integrands.sc, src/macros/macros.sc, src/nd-random.sc, src/oracles.sc, src/utils.sc, CMakeLists.txt, pre-inst-env.in: Add copyright and license headers.
2021-02-26	Rename subsampling-random-vector to cone-random-vector.	Arun Isaac
	* scm/nsmc/wrap.scm: (subsampling-random-vector): Rename to cone-random-vector. * src/nd-random.sc (subsampling-random-vector): Rename to cone-random-vector. * include/nd-random.h (subsampling_random_vector): Rename to cone_random_vector.
2021-02-23	Implement the lower incomplete gamma function as a scheme wrapper.	Arun Isaac
	With this change, the wrapper around the gsl lower incomplete gamma function is directly in scheme. Earlier, there was one layer of wrapping in C which needed to be wrapped again in scheme. * include/utils.h (lower_incomplete_gamma): Delete function. * src/utils.sc (lower-incomplete-gamma): Delete function. * scm/extent-sampling/wrap.scm (lower-incomplete-gamma): New function.
2021-02-23	Provide test integrals.	Arun Isaac
	* include/integrands.h, src/integrands.sc: New files.
2021-02-23	Redefine integrand_t as a struct.	Arun Isaac
	This change will make it easier for the scheme wrapper to curry integrands. * include/extent-sampling.h (integrand_t): Redefine type as struct. (integral): Pass pointer to integrand_t. * src/extent-sampling.sc (integral-per-direction, integral): Handle new integrand-t type. (invoke-integrand): New sc macro.
2021-02-11	Pass extent-oracle-t as pointer.	Arun Isaac
	* include/extent-sampling.h (volume, volume_window, integral, volume_cone, volume_experiment): Pass extent_oracle_t as pointer. * src/extent-sampling.sc: Likewise.
2021-02-11	Change extent oracle and true volume prototypes.	Arun Isaac
	This change will make it easier for the scheme wrapper to curry extent oracles. * include/extent-sampling.h (extent_oracle_t): Define as a struct that bundles the parameters required by the actual extent oracle. * include/oracles.h (bernoulli_params, uniform_params, beta_params, cube_params, ellipsoid_params, spheroid_params): New types. (bernoulli_extent_generator, uniform_extent_generator, beta_extent_generator): Rename to bernoulli_extent_oracle, uniform_extent_oracle, beta_extent_oracle respectively and change to the new extent oracle prototype. (bernoulli_true_volume, uniform_true_volume, beta_true_volume, cube_extent_oracle, cube_extent_oracle_with_center, cube_true_volume, ellipsoid_extent_oracle, ellipsoid_true_volume, spheroid_extent_oracle, spheroid_true_volume): Change to new extent oracle and true volume prototypes. * src/oracles.sc: Likewise. * src/extent-sampling.sc (invoke-extent-oracle): New macro. (volume, volume-window, integral, volume-cone): Call using new extent oracle prototype.
2021-02-11	Include gsl_vector.h instead of gsl_blas.h.	Arun Isaac
	* include/oracles.h: Include gsl_vector.h instead of gsl_blas.h.
2021-02-11	Remove cube maximum extent function.	Arun Isaac
	We are not using maximum extent functions anymore. * src/oracles.sc (cube-maximum-extent): Delete function. * include/oracles.h (cube-maximum-extent): Delete function declaration.
2021-02-05	Remove unused geometric progression functions.	Arun Isaac
	* include/utils.h (gprate, gpterm): Delete function prototype declarations. * src/utils.c (gprate, gpterm): Delete functions.
2021-02-05	Remove unused extent oracles.	Arun Isaac
	* include/oracles.c (symmetric_spiral_extent_oracle, right_triangle_extent_oracle, right_triangle_true_volume, sphere_extent_oracle, sphere_maximum_extent, plane_extent_oracle): Delete function prototype declarations. * src/oracles.c (symmetric_spiral_extent_oracle, right_triangle_extent_oracle, right_triangle_true_volume, sphere_extent_oracle, sphere_maximum_extent, plane_extent_oracle): Delete functions.
2021-02-03	Move source files and headers to separate directories.	Arun Isaac
	* extent-sampling.h, gaussian-nd-random.h, nd-random.h, oracles.h, utils.h: Move into include directory. * extent-sampling.c, gaussian-nd-random.c, nd-random.c, oracles.c, utils.c: Move into src directory. * CMakeLists.txt: Set include as include directory. Look for source files inside src directory.
