log anyway).

Removed decimal precision formatting from String() string for MultiLayerNet.

Nick Poorman
8507a0cba8 Removed decimal precision formatting from String() string for MultiLayerNet. 
Convergence and LearningRate values less than 0.00, ie. 0.003, were being printed as 0.00 which was incredibly misleading when debugging.

581451d726 metrics/pairwise: correct goconvey-related problem 
goconvey's ShouldPanicWith never seems to succeed,
this patch weakens the condition to ShouldPanic.

e30ff6580a ARFF import/export, CSV export, serialisation 
* Only numeric and categorical ARFF attributes are currently supported.
* Only the dense version of the ARFF format is supported.
* Compressed format is .tar.gz file which should allow extensibility.
    * Attributes stored using JSON representations.
* Also offers smarter estimation of the precision of numeric Attributes.
* Also adds support for writing instances to CSV

7ba57fe6df trees: Handling FloatAttributes. 
This patch adds:

	* Gini index and information gain ratio as
           DecisionTree split options;
	* handling for numeric Attributes (split point
           chosen naïvely on the basis of maximum entropy);
	* A couple of additional utility functions in base/
	* A new dataset (see sources.txt) for testing.

Performance on Iris performs markedly without discretisation.
