NodeJS wrapper for GMT

Hi all,

My name is Davide de Lerma, during my past experience I used GMT and I liked the functionalities provided by this tool. I would like to create a NodeJS wrapper for GMT.
Many people are starting creating isomorphic web apps so having a wrapper for GMT in NodeJS could help this kind of users to use the GMT functionalities directly in their JS code.
Thanks to the kind help of @leouieda for creating this repo.
This is first add-on I write for nodeJS so any kind of help and contribution will be very appreciated.
I tried to install gmt with Anaconda following the guide on https://github.com/conda-forge/gmt-feedstock.
Unfortunately I am still not able to use GMT as I got the following error when I run the `gmt` command: `dyld: Library not loaded: @rpath/libgdal.20.dylib
Referenced from: /anaconda/bin/gmt
Reason: Incompatible library version: gmt requires version 24.0.0 or later, but libgdal.20.dylib provides version 23.0.0
[1] 35357 abort gmt`
The GDAL version I am using is `GDAL 2.2.2, released 2017/09/15`
