Generates a table of the annotated genes for mouse genome (GRCm39) from the ensembl database. Using the R-packages biomaRt to pull gene data. Table consists of 10 columns:

1. chr Chromosome ID.
2. start Gene start.
3. end Gene end.
4. strand Strand info, given in +, - or * forward, reverse or no info, respectively.
5. gene_id Ensembl gene ID
6. gene_name External gene name
7. entrez_id Entrez ID
8. gene_info Gene discription
9. gene_type Protein coding, non-coding RNA, pseudogene etc
10. gene_type2 A concatination of the gene types where the micro RNAs are label ncRNA and all pseudogene variants are labeled pseudogenes
