Math activity

A math activity computes an arithmetic expression using the message's attributes. The expression must return a number. For example, given the following input message:

{ "tempF": 50, }

after processing by the following math activity:

{ "math": { "name": "MyMathActivity", "math": "(tempF - 32) / 2", "attribute": "tempC", "next": "MyDatastoreActivity" } }

the resulting message looks like:

{ "tempF" : 50, "tempC": 9 }
