Add fake data for medical terms

[sonisnehal]

I am working on the Health care software company and I am using faker heavily to use random data. It would be great if we could add some health care related terms, like diseases, therapuratic area and few other things like all tests, ie.e 12 Lead ECG, Blood test.
