This is for internal use. It converts the NCBI exon annotations into data files for use in the detectionCall
function.

This is an internal function and should not be called by users directly.
It processes annotation of genes in human genome GRCh37/hg19 or mouse genome GRCm37/mm9. The annotation is available for download from the following links (these annotations include chromosomal coordinates of UTR and CDS regions of genes):
ftp://ftp.ncbi.nlm.nih.gov/genomes/H_sapiens/ARCHIVE/BUILD.37.2/mapview/seq_gene.md.gz
ftp://ftp.ncbi.nlm.nih.gov/genomes/M_musculus/ARCHIVE/BUILD.37.2/mapview/seq_gene.md.gz
This function finds the chromosomal coordinates of intergenic regions (regions between neighbouring genes) and then outputs them to a file.
It also outputs to a file chromosomal coordinates of exons of genes by concatenating UTRs with CDSs and merging overlapping CDSs within each gene.
The generated annotation files will then be used by detectionCallAnnotation
function to produce annotation data required by detectionCall
function.
Two annotation files are written to the current working directory. This function returns a NULL
object.
