Added proper full definitions for the methods of the AIS multivariate interface; much of this is achieved by extending the univariate AIS interface (which mandates that the univariate methods must be supported). No current child classes required any changes as they all supported these already. Removed superfluous documentation in the AIS multivariate via MI class (as well as fixing whitespace inconsistencies therein)

Added new interface InfoMeasureCalculatorContinuous to capture common methods for continuous calculators. Also adapted most continuous calculators to implement this, which involved in many cases removing duplicate definitions of these methods in the interfaces for these measures. For ConditionalMI calculator, this meant we needed to add an implementation of the zero-argument initialise() call also. Still need to do MultiInfo, PredictiveInfo and Entropy in future, as they're missing a few methods.

Altering various continuous calculators to implement the EmpiricalNullDistributionComputer interface (where they're already implementing computeSignificance() etc.). Also altered the EmpiricalNullDistributionComputer methods to throw Exceptions, since the continuous calculators generally do this (and doesn't harm the discrete ones). Also involved implementing the methods in ConditionalMIMultiVariateCommon by selecting to permute the first variable by default.

Javadocs made release-ready in the continuous package. Also added computeLocalUsingPreviousObservations into ChannelCalculator and ChannelCalculatorMultiVariate (removed from MutualInfoMultivarate), and made the ViaCondMutualInfo classes not be abstract anymore, and moved embedding properties up into the main TransferEntropyCalculator interface

Added interface for ConditionalTransferEntropy. Added abstract implementation ConditionalTransferEntropyCalculatorViaCondMutualInfo, and child classes for Kraskov and Gaussian implementations.
...
Added associated embedding method to MatrixUtils, and fixed a lot of header comments here. Minor fixes to comments and which methods are specified (e.g. setProperties) for TransferEntropy and Entropy calculators.

Added TransferEntropyCalculatorViaCondMutualInfo to allow calculation of TE via any implementation of a conditional MI calculator. Added concrete implementations using this for Gaussian estimators (Gaussian TE estimator is equivalent to Granger causality). Replaced existing Kraskov TE calculator (which used two MI calculators) with one which uses one conditional MI estimator via this new method. Also patched TransferEntropyCommon.computeStartAndEndTimePairs

Added ActiveInfoStorageCalculatorViaMutualInfo to allow calculation of AIS via any implementation of an MI calculator. (Forgot to add this before -- its child classes are already committed).

Rearchitected Active Info Storage calculators to use a common parent class for data collection, and underlying mutual information classes for the implementation specifics. Includes adding Kraskov and Gaussian Active Info Storage calculators, and implementing embedding delay for the past history.

Added classes for joint entropy and multivariate mutual information calculation with gaussian assumption.
...
Restructured MeasurementDistribution to have child classes EmpiricalMeasurementDistribution and AnalyticMeasurementDistribution - this resulted in many classes being altered.
Added ChiSquare distribution methods to MathsUtils.
Added more covariance methods to MatrixUtils.
