OWA generator improvement

@pascal

Till we get some views on this API, we can discuss about the use of FHIR module in our generator. I have some thoughts about it.

As you mentioned in the comments on the proposal that we need some easy way to use the FHIR module. So, what I am thinking is we can design a new FHIR component where we will be fetching the server context or url and then design some small functions there (for create, delete, etc) so that any user using that could use the desired functions from there to perform their required operations whether they will be using openmrs SDK or standalone. After that, we can include a demo having a short form to show how to use it to create a new patient.

Could you feel it good ?
