addSection
Add a new empty named section to the SWML document. Sections are named
containers for ordered lists of verbs. Every document starts with a main
section — use this method to create additional sections (e.g., a transfer
flow).
Silently no-ops if a section with the given name already exists. Follow up
with addVerbToSection() to populate the section.
Parameters
sectionName
Name of the section to create.
Returns
this — returns the builder for fluent chaining.
