Add arms, interventions and outcomes to an existing xml document for upload to clinicaltrials.gov

These functions add arms, interventions, primary and secondary outcomes as well as conditions and keywords to an xml document created using the create_ctxml() function. Calls to these functions should not be assigned to an object.

Usage
add_arm(ctxml, arm_label, arm_type, arm_desc)

add_intervention(ctxml, int_name, int_type, int_desc, arm_label)

add_pr_outcome(ctxml, name, time, description)

add_sec_outcome(ctxml, name, time, description)

add_condition(ctxml, condition)

add_keyword(ctxml, keyword)

Arguments
ctxml

A xml document generated from the create_ctxml() function

arm_label
