Organization of genotype database

[gaow]

Currently in my project folder I see:

[GW] ll *.DB
-rw-r--r-- 1 gaow gaow    0 Mar 22 11:34 VATDemo_genotype.DB
[GW] ll *.h5
-rw-rw-r-- 1 gaow gaow 3.1M Mar 22 11:38 tmp_1_90_genotypes.h5
-rw-rw-r-- 1 gaow gaow 5.4M Mar 22 11:38 tmp_91_202_genotypes.h5
-rw-rw-r-- 1 gaow gaow  11M Mar 22 11:39 tmp_1_90_genotypes_multi_genes.h5

That is, 1) empty genotype DB file, which is confusing and 2) a number of random h5 files with tmp in the file names, which makes me feel I aught to be able to delete them at any time ... which apparently should not be the case because they are actually data!

Shall we get rid of 1) and move these other genotype files to a folder to keep it neat, and also name them better?
