Here are the classes, structs, unions and interfaces with brief descriptions:

NAnalysisTree	Cuts keep list of SimpleCuts. Logical AND is applied for all SimpleCut in the Cuts object
NUtils
CVisitor
CAnalysisEntry	AnalysisEntry keeps list of Variables from one or more branches. Before each event AnalysisEntry evaluates Variables and Cuts
CAnalysisTask	AnalysisTask is a Task which keeps list of AnalysisEntry-s It evaluates Variables according to the rules of AnalysisEntry-s and populates 2-dimensional array with results of evaluation
CBranch
CFieldsMapping
CBranchChannel
CBranchConfig	A class to store configuration of the Container
CChain
CChainDrawHelper
Cclear_channels_struct
CConfigElement	Information to store about a data field in Configuration
CConfiguration	A class to store configuration of the whole AnalysisTree object
CConfiguration_v3	Some ROOT magic, ask Eugeny
CContainer	A class to store any number of doubles, floats, integers and bools
Ccopy_content_struct
CCuts	Cuts holds list of SimpleCuts and provides Apply function which subsequently applies cuts
CDataHeader
CDetector
CEventHeader
CFIB
CField	Field is a pointer in a branch/field structure
CGenericContainerFiller
Cget_channel_struct
Cget_field_struct
Cget_id_struct
Cget_n_channels_struct
CHit
CIndexAccessor
CIndexedObject
CIndexMap
CLeafBuffer
CMatching
CMatchingConfig	Information to store about Matching
CModule
CModulePosition
Cnew_channel_struct
CParticle
CPlainTreeFiller
Cset_branch_address_struct
Cset_field_struct
CSimpleCut	SimpleCut keeps predicate (lambda function with vector of arguments) and list of Variables
CTask
CTaskManager
CToyMC
CTrack	A class for a generic track with determined momentum
CVariable	Variable is a wrapper object for Field. In contrary to Field Variable is not bound to the data. It could represent a Field itself or, if specified, a result of operation on two or more fields
CVectorConfig	Template class to store configuration, e. g. name and description of the vector element
CUserTaskRead
CUserTaskWrite
