Will first validate, normalize, and then print tabular data according to the style
named in the arguments list. Validation will remove any malformed submodule
transclusions to ensure one bad entry doesn't break the entire display. Normalization
ensures that the desired key-value pairs exist (still working through the details on
how this should be implemented.  Display is self-explanatory.
 
The goal of this module is to provide a more resilient means of supporting both
human- and machine-readable and writable data.
 
Usage to print a members' table, for instance: 
{{#invoke:ListMaster|printTable|style=[table|section]|display=[...]|
  {{#name=name1|role=role1|member_since=date1}}
  {{#name=name2|role=role2|member_since=date2}}
  {{#name=name3|role=role3|member_since=date3}}
  {{#name=name4|role=role4|member_since=date4}}
}}
