VCF to GFF3 Converter script, a contribution to Bioinformatics community

Back in April, my boss generated lots of SNP/indels and he intends to have it displayed on the web portal I'm developing for the use of the C4 Rice Project Consortium Members. I was stuck for a long time looking for a pre-existing software/script to do the job. It is because per experience, the task seems so simple so most probably there could be a lot of existing ones somewhere out there.
