SetParentSectionAndDocVersion to eliminate lookups when the parent is known.

Browse Source 
Use existing ActiveSection rather than "getting" an item from the database.
Add property "LoadAllAtOnce" for printing.
Allow MyProcedure to be set for "LoadAllAtOnce"
Allow MyDocVersion to be set  for "LoadAllAtOnce"
Created GetCachedByPrimaryKey for ProcedureInfo, SectionInfo and StepInfo.
Added Static Method GetItemAndChildren to get an entire procedure at once.
