Add support for Poisson distribution

[hot9cups]

Go through the Gaussian distribution class, the Binomial class and the Exponential class which are subclasses of General distribution class.

I would like to expand this to include another distribution, the Poisson Probability Distribution.
It should be able to calculate mean, standard deviation, and create basic plots like those in the classes I linked.

Please assign this issue to me, I am new to open source and would like to contribute

@AmeyaPhadnis-2019H1030012G I'd be glad to assign it to you! Before that, could you tell me a bit about how you plan to approach it ?

Hi @hot9cups. If this does not get assigned, I would like to complete this task. To prepare, my plan is to go through the code for the distribution classes, their respective tests in test.py, documentation for matplotlib, read up on poisson distribution, come up with a numbers_poisson.txt for demo data. For the implementation, I'm going to mimic the implementation of the other distribution classes

@ho-jonathan Since AmeyaPhadnis seems to have deserted us(And they also have request for claims on two other issues so if they come back there's always that), I'm assigning it to you.

That plan sounds perfect! Please go ahead!

@ho-jonathan I was wondering how you're progressing with the PR

[hot9cups]

@ho-jonathan are you still interested in working on this? I will assume it's a no if you're unable to respond within a week :(
