org.das2.qds.MutablePropertyDataSet
Some QDataSets allow their properties to be changed. Note scripts should
never assume a dataset is mutable, and should call the putProperty method
instead, which will make a copy if necessary. Note the terms mutable,
writable, and modifiable are all used in this documentation and interchangeable.
isImmutable
isImmutable( ) → boolean
return true if the dataset has been made immutable.
Returns:
true if the dataset has been made immutable.

mutating properties will print warning messages for now, but will soon
be an error.

putProperty
putProperty( String name, Object value ) → void
assign the name value to the property. Note that name__i can be
used as a alias for an indexed property, but when possible
putProperty(name,i,value) should be used.
Parameters
name - property name like "UNITS" (Use QDataSet.UNITS)
value - the property value.
Returns:
void (returns nothing)
