// Procedure Name:
// dynTestAddAttr
//
// Description:
// Test adding user attributes to a particle shape.
// Create a particle object, set its render type to
// streak, and add a dynamic attribute "tailSize".
// The streak render plug-in will use the attribute
// "tailSize" if it is available.
//
// Input Arguments:
// None.
//
// Return Value:
// Number of errors that occurred in the test.
