Calculate Bayes Factor for original Sherlock

1 2	sherlock1(eqtl_pval, gwas_pval, maf, n1, n2, alpha = 5e-05, beta = 5e-04, sigma_a_eqtl = 0.5, sigma_a_pheno = 0.5)

`eqtl_pval`	Vector of p-values for gene expression (length p)
`gwas_pval`	Vector of p-values for gwas trait (length p)
`maf`	Minor allele frequences (length p)
`n1, n2`	sample sizes for eqtl and gwas studies
`alpah, beta, sigma_a_eqtl, sigma_a_pheno`	Tuning parameters (see Xin et al 2011). Default values are alpha=5e-5, beta=5e-4, sigma_a_eqtl = 0.5, sigam_a_pheno=0.5
