 - Made several classes in package `meico.app.gui` package-private as they will never be accessed from outside the package and are not intended to.
 - Made class `meico.msm.MsmBase` abstract and renamed it to `AbstractMsm`.
 - Removed MSM's global header element `pulsesPerQuarter`. Instead an eponimous Attribute has been added to the root note of the MSM.
