Detailed Description

Test of serialization, input and output, for all pdfs.

A random pdf is constructed for each type, serialized and output to a file. A new pdf is constructed from the serialization in the file and compared to the original for equality.

Results are as follows:

GaussianPdf passed
DiracPdf passed
UniformPdf passed
DensityTreePdf passed
GaussianMixturePdf passed
DiracMixturePdf passed
DensityTreeMixturePdf passed
