Dynamic memory allocation

[MathijsV]

There are multiple places in the code where longhair does memory allocation. This is not desirable in a real time environment, because the "new" may take a long time.

Currently, the code has no state object that's passed around, so it has to do "new" calls every time. I would prefer if the library got a state in which memory is kept, so that is does not have to be alloc'ed/dealloc'ed every time it's used.
