selectGenesMtb: Function to select genes from Mtb time course Abx RNAseq data
In nirmalya-broad/GeneSelection: Generate selection method for diagnostics project

This is the main function to generate genes from Mtb Abx RNAseq time course data

1 2	selectGenesMtb(count_file, outdir, stag, sus, treated, untreated, timepoints, l_cand = 1, base_lim = 50, use_t1 = FALSE)

`count_file`	File containing read counts for genes for all samples
`outdir`	Output directory for results and logs
`stag`	A string appeded to the generated files
`sus`	Susceptible strain
`treated`	Condition/compound for treated samples
`untreated`	Condition/control for untreated samples
`timepoints`	timepoints in the time series data
`l_cand`	log2fold change limit for candidate genes [default : 1]
`base_lim`	baseMean limits for a gene after DESeq2 [default: 50]
`use_t1`	Set it to use first time point [default: FALSE]
