Handle multiple regions

[jhowlett-scottlogic]

current the simple bash scrip handles only 1 region. THis is because ti retreives the first regions optimalDataPoints object but each region generates this.

we ideally want to be able to put in an array of regions and then have the most optimal region and time outputted.

THis will require changing from using bash scripts to using something more sophisticated that uses json object parsing. (wait for #18 to be compelted)
