## Detailed Description

An object of this class maintains a connection between a ComboBox and a plug-in parameter.

ComboBox items will be spaced linearly across the range of the parameter. For example if the range is specified by NormalisableRange<float> (-0.5f, 0.5f, 0.5f) and you add three items then the first will be mapped to a value of -0.5, the second to 0, and the third to 0.5.

During the lifetime of this object it keeps the two things in sync, making it easy to connect a combo box to a parameter. When this object is deleted, the connection is broken. Make sure that your parameter and ComboBox are not deleted before this object!
