Implement if procedure

[jfrioux]

Implement the if Leaf Procedure.

Review how Floristry::ParametersInterpreter handles Flor constructs.

---

We need to display in the _if.html.erb partial the condition, the else, and their sequences:

View

if (1=1)
  ▼ sequence ▼
    do_this
else
  ▼ sequence ▼
    do_that

Flor definition

if (1=1)
  sequence # then
    do_this
  sequence # else
    do_that

Solution should define a reusable pattern for the other 2 unimplemented procedures: concurrence and cron.

Im really unsure of what you are talking about here. An if basically have the same representation as the concurrencen: two paths. The only difference is only one of the path is ever used and the partial needs to display the condition. Also, concurrence is implemented, just like sequence. Please explain.

Will be working on accessing the payload from the if to enable decisions based on the workflow's context.

Well need to define our communication format/standard. We should inspire ourselves from Unix.
