Create an example for building bio NER pipeline

[Tianyang Liu]

Describe the solution you'd like

In ForteHealth, we incorporate ScispaCy for bio ner annotation, I think, as the very first example, we can simply create a pipeline for bio NER annotation. The demo from scispacy is here

In scispacy, with model en_ner_bc5cdr_md, we can annotate Disease and Chemical, with model en_ner_bionlp13cg_md, we can annotate Cancer, Organ, etc. We can also show this by using different configuration to build the pipeline.

Possible included componets:

1. Sentence Segementor
2. Tokenizer
3. Bio NER Tagger
