"""
Add a variable to each particle in this swarm. Variables can be added
at any point. Removal of variables is however not currently supported.
See help(SwarmVariable) for further information.
Parameters
----------
dataType: str
The data type for the variable. Available types are "char",
"short", "int", "float" or "double".
count: unsigned
The number of values to be stored for each particle.
Returns
-------
variable: SwarmVariable
The newly created swarm variable.
