write an helper to transform ${linkid} to fhirpath in Expression

[delcroip]

${linkid} will need to be translated to

%resource.repeat(item).where(linkId='4.2.1').answer.value

e.g. so to check a code one will have to write ${linkid}.code

see reason here google/android-fhir#819

@delcroip and in your example, if you write ${linkdid}.code in the excel file you should get %resource.repeat(item).where(linkId='linkid').answer.code in the JSON ?
