Asynchronously read a comma-separated value file. Returns an empty array if file is empty.

@function readCsv
@param {String} filePath Input file path
@param {Function|Object} [map] Optional map function or an object with `map` key that is a function. Called once for each row with the signature `(row, i)` and must return the transformed row. See example below or d3-dsv documentation for details.
@param {Function} callback Has signature `(err, data)`

@example
io.readCsv('path/to/data.csv', function (err, data) {
console.log(data) // Json data
})

// Transform values on load
io.readCsv('path/to/data.csv', function (row, i, columns) {
console.log(columns) // [ 'name', 'occupation', 'height' ]
row.height = +row.height // Convert this value to a number
return row
}, function (err, data) {
console.log(data) // Converted json data
})

// Pass in an object with a `map` key
io.readCsv('path/to/data.csv', {map: function (row, i, columns) {
console.log(columns) // [ 'name', 'occupation', 'height' ]
row.height = +row.height // Convert this value to a number
return row
}}, function (err, data) {
console.log(data) // Converted json data
})
