Changes

Described more thoroughly here: #835 . AI below:

• Upgraded the build_schema.py module so that it fixes typos on the fly.
  • Now description always ends in . (Unless finished in a )) and has no spaces at the beginning or the end
  • Now examples are the same type as the field
• Upgraded the build_schema.py module to reference enums in $defs and move them to the end.
• Update the schema excel file to add the identifiers_org_prefix keyword in options
• Updated template in repository to 3.2.4

You declare enum_defs = json_schema.get("$defs", {}).get("enums", {}) before, leaving the possibility of this variable to be an empty dict. In that case this line would crash without option to track the original error. I'd suggest adding a try/except clause either here or in the definition of enum_defs

Good catch! Many thanks :) I've updated it so that this exception is caught by property, so if multiple property enums are missing from defs (maybe in the future we add something that deletes some by accident) it spits the error like this (Example for missing "organism" enums):

...
Enter a note about changes made to the schema: asads
Error finding enum for property 'organism'; not found in $defs
Metadata lab template successfuly created in: 
...

Right now it does continue generating the template and finishes somewhat successfully (No enums for those properties, though), I could raise an error and exit or leave it like that. What do you prefer?
