ensemblQueryGetPops     Function to get list of populations that
                        Ensembl has available to query LD.
ensemblQueryLDwithSNPpair
                        Function to query Ensembl LD data with a pair
                        of rsIDs. This function will return r-squared
                        and D' values for the rsID pair.
ensemblQueryLDwithSNPpairDataframe
                        'ensemblQueryLDwithSNPpairDataframe' applies
                        'ensemblQueryLDwithSNPpair' to a data.frame of
                        rsID pairs
ensemblQueryLDwithSNPregion
                        Function to query Ensembl LD data within a
                        genomic window to get all variant pairs in the
                        specified region and associated LD metrics.
ensemblQueryLDwithSNPregionDataframe
                        'ensemblQueryLDwithSNPregionDataframe' applies
                        'ensemblQueryLDwithSNPregion' to a data.frame
                        of genomic coordinates and returns all variant
                        pairs present in each specified genomic region
                        and their associated LD metrics.
ensemblQueryLDwithSNPwindow
                        Function to query Ensembl LD data with a single
                        rsID
ensemblQueryLDwithSNPwindowDataframe
                        'ensemblQueryLDwithSNPwindowDataframe' applies
                        'ensemblQueryLDwithSNPwindow' to a data.frame
                        of rsIDs.
pingEnsembl             Function to check whether the Ensembl server is
                        up by pinging it.
