Logical functions

All of the logical functions return a boolean type. These functions allow various conditions to be tested. Types have order of precedence. When comparing values of different types, they are ranked in the following order, from greatest to least. For example, a double is sorted before an integer because of its type.

Nulls
Doubles
Booleans
Dates
Times
Refs
Objects
Arrays
Strings
Integers

`And`	Returns true if all values are true.
`Contains`	Returns true when an object path points to an object’s value.
`Equals`	Returns true of all values are equivalent.
`Exists`	Returns true if an instance has an event at a specific time.
`GT`	Returns true if each value is greater than all following values.
`GTE`	Returns true if each value is greater than, or equal to, all following values.
`LT`	Returns true if each value is less than all following values.
`LTE`	Returns true if each value is less than, or equal to, all following values.
`Not`	Returns the opposite of a boolean expression.
`Or`	Returns true if any value is true.
