The crate documentation is confusing: I'm not exactly sure what this is generating in batch mode?

The documentation says that it generates all "permutations" of a given sequence: the documentation for utils::gen_sequences() shows an example with two identical notes (C:4, C:4). On the other hand, gen_sequences() appears to generate a Cartesian Product of note sequences of the given length vi

Reading gb_math.h source sometimes is really confusing.
Usual math notation for matrix is Aij where i is row and j is column:

A00 A01 A02 A03
A10 A11 A12 A13
A20 A21 A22 A23
A30 A31 A32 A33

Note that this notation is memory-layout free, this is just how matrices are written down on paper in generic science/engineering notation.

Considering this:

typedef union gbMat4 {
	st

For example, it seems like .travis.yml uses cmake (for the tests), so this is a cmake project that pops out a library that I should link against (it seems not - cmake is just for tests?)? If I look at a module like cpu that has cpu.h and cpu.c do I just drop those into my project (probably not that simple since they may depend on other modules)?

Maybe something like a default-use case s

In the first two entries should "California" be the author? What about the second two.
