initial checkin of extracted geom-core sub-project only containing protocol defs and refactored vectors, matrices & quaternion impls

Quat4 now implements same Clojure protocols as Vec2/3
Vec2/3 & Quat4 have no more metadata support
refactored swizzling fns, add swizzle for Quat4
move & update existing tests from parent into new sub project
addresses #3 refactor matrix types as deftype, but still need standard clojure protocol impls
revert api ns back into geom.core, update various math expressions, bugfix swizzle for quat
migrate other protocols into new geom.core, distribute PMesh into PFace/NormalAccess, add PGeomContainer, update babel codeblock structure using noweb-ref's
update babel codeblock structure using noweb-ref's, add templates to vector ns
migrate & refactor various common functions from old geom.core into new geom.core.utils ns
add *resolution* dynvar to core, add delta-contains to utils
Merge branch 'feature/geom-core' into develop

  initial checkin of extracted geom-core sub-project only containing protocol defs and refactored vectors, matrices & quaternion impls
initial import of refactored & restructured type namespaces as thi.ng/geom-types sub-project, only a backup commit, untested & highly erroneous
bugfix & refactor bounding-rect/box fns, add shared bounds* fn
update & bugfix aabb
Merge branch 'feature/geom-types-refactor' into develop

* feature/geom-types-refactor:
  update & bugfix aabb
bugfix & update utils/centroid
bugfix utils/center, add scale-size & triangle area/clockwise fns
update library-of-babel templates
bugfix & extend PFaceAccess & PNormalAccess protocols
fix namespace ref for bounding-circle/sphere templates
add core geom.types ns & new freeform box type impl
add msub & subm to PMathOps, implement for Vec2/3, refactor tests for dual math ops
update/extend AABB impl

add PFaceAccess
update defaults for subdivide (same as Box type)
update tesselate
update transform methods to return Box type where needed (e.g. rotate, transform)
