Version 0.7.4

This is primarily a bugfix release.

export:

• bed --show variant now filters CNAs on sex chromosomes correctly, taking reference and sample genders into account.
• nexus-ogt format now emits BAFs more similar to the original VCF allele frequencies. Previously, if multiple SNVs fell into a single CNVkit genomic bin, the allele frequencies of those SNVs would all be "mirrored" above 0.5 before taking the median. Now the SNVs are mirrored in the direction of the majority of the SNVs in the bin, whether above or below 0.5, so that the output looks more balanced and low-frequency SNVs are more apparent.

heatmap:

• Sub-chromosomal regions can now be selected for display with the -c option, e.g. -c chr7:125000000-145000000, just like the same option in scatter.

segment:

• Fix the listing of gene names in each segment in the output .cns file. Previously, briefly, each gene's name was truncated to 1 character.
