make genotype/call subfields accessible
allow for the FILTER column to have additions
Read all variants into memory for compound (biallelic) filtering

This address the issue that in rare occasions, exons from
different genes can interleave or overlap
Changes to non-vcf output:

add DV to FORMAT reordering
set COLUMNS_TO_HIDE as Strings instead of integer indices
FORMAT is not required in VCF files-- avoid null pointer
support for additional headers in javascript filter
Allow groovy as a scripting language for filters

Using the -g option instead of -f... This can be
significantly faster than javascript.
filter on ESPMAF as well
only add a filter if it is not already present
upgrade gradle wrapper to 1.7
write INFO values over multiple lines for lists of items

I am not sure if I will leave this in long-term-- it makes
some of the rows very tall. It may also be good as an option
(but I have not worked out how I would allow for configuration
of the excel-file-writer from the command line).
update to apache poi 3.9
auto resize all columns and rotate the headers
Switched to XSSF

This makes the jar file a lot bigger (adding groovy went 2.2->6.1mb,
now adding groovy + poi-ooxml makes 15mb). But compared to the size
of the datasets... and the .xlsx files are smaller than .xls, so the
size gets amortized away. It may be nice to separate out the xls-making
part at some point, though.
add the ability to specify a 'description' for a tsvAnnotator line

This configuration keeps getting more and more overloaded... I may
need to make a DSL out of this.
move columns around in the excel output:

move the genotypes earlier in the file (before INFOs)
move 'Gene_name' earlier in the columns if it is present in the INFOs

This is really hacky, I do not like the code, but I like having to
scroll to find the gene name even less...
Switch over to htsjdk.

With incorporation of tribble, some of my code (e.g. for tabix handling)
can probably be cleaned out.
update default config.js for dbNSFP2.4
nashorn is stricter about javascript and will not allow "with", so we need to spell out a variable
upgraded poi to 3.10-FINAL (significantly faster writing for some large xml files)
