Specify multiple evaluation criteria and run an action if the criteria
evaluates to true.

- cond:
   - (@ user.age < 18):
       flow: flow.confirm_age
   - (@ user.age >= 18 and user.age < 65 ):
       jump: next
   - (@ user.age >= 65):
       flow: flow.retired
  default: next

Similar to the flow.if component's
if field, the evaluation criteria must evaluate to either true
or false, and thus we can use Meya template syntax to
create complex evaluation criteria using a combination of template operators
and flow/thread/user scope variables.

Also, each condition in the cond field must contain a valid action field,
meaning the field takes an action spec which maps to the ActionComponentSpec
Python class. This allows you to execute any component, but you will mostly
use one of the flow control components.

Fields

field	description	required	signature	default	type
spec	Override the original spec for this element.	○	○	null	Spec
context	Send context data with this component's event.	○	○	{}	dict
sensitive	Mark this component's event as sensitive. This will encrypt the event if the Sensitive Data integration has been enabled.	○	○	false	bool
triggers	Activate these dynamic triggers when the component runs. Check the component triggers guide for more info.	○	○	[]	list
cond	Contains a set of evaluation criteria that will be evaluated in order starting with the first evaluation criteria. The evaluation criteria is expressed using Meya's template syntax.	◉	◉		list
default	This is the default action should none of the evaluation criteria evaluate to `True`.	◉	○		ActionComponentSpec
