Time-Based Analysis Operators

Operator	Description
Time Assignment	x?=y Used in groups to define the value of a node at different times. For example: ``` Sales:={
t<=2005?=100;
t==2006?=150;
Sales{t-1}*1.10;
} ``` In this example, Sales has a value of 100 in 2005, 150 in 2006, and grows at a rate of 10% in every subsequent year.
Time Value	x{y} Read the value of a node at different times. For example: ``` Sales{2005}
Sales{2005..2010} ```
