Input
------
Peregrine takes a single population protocol as input.
The following example shows how a protocol is encoded:
Peregrine takes a single population protocol as JSON-encoded input.
The following example shows the input format:
```
population protocol "Majority Protocol" {
states { a b a_small b_small}
transitions { t1 t2 t3 t4 }
arcs { { a, b } -> t1 -> { a_small, b_small }
{ b, a_small } -> t2 -> { b, b_small }
{ a, b_small } -> t3 -> { a, a_small }
{ a_small, b_small } -> t4 -> { a_small, a_small }
}
initial { a b }
true { a a_small }
false { b b_small }
{

"states": ["A", "a", "B", "b"],
"transitions": [
{ "name": "t1",
"pre": ["A", "B"],
"post": ["a", "b"]
},
{ "name": "t2",

}
],
initialStates: ["A", "B"],
trueStates: ["A", "a"],
predicate: "A >= B",
description: "This protocol computes whether there are more B-states than A-states"
}
```
* After the keyword *population protocol* the name of the protocol is given in
quotes.
* Finite sets are specified in braces
through space- or comma-separated lists of names.
Names consist of alphanumerical characters or underscores.
* The set of states is given after the identifier *states*.
* In order to make transitions identifiable,
each transition must be given a name after the keyword *transitions*.
* Transitions are defined after the keyword *arcs*; there must be one definition
for each transition name.
* The set following the keyword *initial* specifies states that can
belong to an initial population.
* The sets following the keywords *true* and *false* identify the states
that map to true and false, respectively.
