Improving doxygen documentation for files in DSP FilterLib, adding yaml file to Xcode project
Adding non-functional mute-solo effect, more work needed before it's ready for prime time
Fixing some typos from commit earlier today that caused weird doxygen formatting
Minor updates, cosmetics and doxygen
Implementing methods for setting and getting mute and solo settings, but they are not tested yet,
More work on mute solo - now works as a regular DSP external in Max
Adding some macros to the doxygen macros group
Adding comment from Skype session yesterday, eventually this will need to be included in Doxygen documentation, and probably we'll want a separate intro page on how to create extensions that use this as an example.
Merge branch 'feature/15-mute-solo' into dev
Fixing two errors discovered while developing implementation tests:

1) mute flag was not properly treaded as a boolean
2) solo flag was not properly treaded as a boolean
Ensuring that macro shows up in doxygen
Adding doxygen comments to most of the type enumerations.
Jamoma DSP: Adding new type TTChannelCount and a new constant kTTMaxChannelsPossible , these can be used whenever storing, addressing ro processing multichannel signals in DSP and AudioGraph.
Ensuring that mute and solo states are stored for channels that goes beyond the current maximum number of channels. This is needed for the AudioGraph implementation (j.mutesolo=) to work properly. When that object instantiates, it only have one channel, and this only change when it starts processing audio. If mute and solo settings are being initialised before audio is on, they are likely to set mute and solo values for channels that the object is not yet planning to process, and all of these just have to be stored for the time being, so that the object later on can make use of the settings.
Adding 10 assertions to TTMutesolo and they all pass! relates to #292

Might be that the test have deprecations, but that we'll need to find out when merging into the api_andapi-cleanup branch.
Substituting TTUInt16 for TTChannelCount where relevant throughout EffectLib - #293
Adding a few comments for improved readability
Substituting TTUInt16 for TTChannelCount where relevant throughout AnalysisLib - #293
Substituting TTUInt16 => TTChannelCount where relevant in TTAudioEngine extension - #293
Substituting TTUInt16 for TTChannelCount where relevant, and improving Doxygen documentation
