initial transition from notebook
crace
added tests
let L not be a return argument but input/output argument in C; add libgsl as dependency
LBA pdf/cdf in C with tests
can now reproduce loglikelihood-output from andrew

there was a mixup in the ter subtraction; I outsourced
it into the LBA-pdf/cdf functions
halfway through SSLBA likelihood\n

need to take care, that the integers are properly send to the C-code! np.int32
