Detailed Description

An object of this class maintains a connection between a ComboBox and a parameter in an AudioProcessorValueTreeState.

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 ComboBoxAttachment 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 AudioProcessorValueTreeState and ComboBox aren't deleted before this object!
