refactored the method computing the log-likelihood, so that the partial log likelihoods can be computed seperately
Added maximum number of iterations to compuation of eccentric anomaly
Version 0.11
* minor bug fixes
* Added method to return the log-likelihood of every individual star (instead of only the total log-likelihood for all stars)
Fixed iteration in multi_epochs, when only a single mass is defined
Fixed bug, where the code would crash if a single mass was given
Adjusted log_likelihood_detection so that it adds log-likelihoods instead of multiplying likelihoods to stop it from overflowing in the case of a large dataset
Version 1.2:
* bugfixes
