this function should handle initTags that still contain tags once the initCollection is finalized, then process the deferred body tags the notion is that the substitutions will be handled in an inefficient manner -- using lots of regular expression parsing, not using the matched tags data.frame
finalizeInitCollection(initCollection)Finalized initCollection
The list of all arguments parsed from the init section
we only need to handle simple and array tags iterators should always be integers foreach and conditional are not relevant
iterate over init tags until no tags are left here, the init collection should already have had most of its tags substituted by replaceInitTags above.
