Replaced lists for memoryviews of numpy arrays. Replaced lambdas for an inlined cdef function. General speed up of 300x. Yeah. My old code sucked.
Just to follow the new name convention for Cython modules. Doesn't really make sense to have a python alternative to many modules because they wouldn't run in a reasonable amount of time. So modules that have no alternative _*.py module don't need the 'c' in the beginning.
Don't need it because of new speedups. It's not longer a bottleneck as the serial version is 300x faster than the old parallel version.
Included entry on speedup of seismic.ttime2d
It read fatiando_seismic_ttime. Missing the 2d

Updated the Cython code of the straight ray travel-time calculation.
It now uses some memoryviews instead of lists and inlined cdef
functions instead of lambdas. The result: > 300x speed up!
And that is when comparing the old parallel code with a serial run
of the new code.
In short, Cython rocks.
