geneFilter: Filtering for Low Count and Low Variance Genes
In yunzhang813/rGTExNetwork: Co-Expression Network Analysis on GTEx Data

Gene filtering based on the mean expression level and standard deviation for each gene across samples.

1	geneFilter(dat, mean.thred, sd.thred)

`dat`	Expression matrix with genes in columns and samples in rows.
`mean.thred`	Threshold for mean.
`sd.thred`	Threshold for standard deviation.

Indices of genes that should be kept after the filtering.
