lua-ctables

Memory Transfer between multi-dimensional Lua-tables and
C-arrays (void* ptr)
* Lua-tables of any dimension
* C-arrays/buffers of any type

C-buffers of any type means module can be used for IPC for
example shared/file-mapped memory. If layout matters this
feature is limited to IPC where both sides interpret long
double and integers the same.

Included is a linear algebra Vector/Matrix class capable of non
accelerated linear algebra using familiar operators. The class
primary use-case is to test/verify the module.
