Automated Mapping of field to concept_id

[erummas]

Currently the mapper only supports automated field value mapping but not field mappings

Suggestion :

• Make use of the dictionary to generate mappings
  Current format for dictionary is
  csv_file_name | field_name | code | value
  abc.csv | condition | icd10

Presently we are required to provide csv_file_name , field_name and code for field value mapping. I'd recommend we use this to map field instead of field values.

In order to map field values we could make use of the 'value' column and use a key word such as 'map_all_values' to suggest it's a field value mapping.
csv_file_name | field_name | code | value
abc.csv | condition | icd10 | map_all_values
