Made bigint use explicit relational operator functions rather than the overly
...
general templates in dlib::relational_operators. I did this because the
templates in dlib::relational_operators sometimes cause clashes with other
code in irritating ways.

Changed test_regression_function() and cross_validate_regression_trainer() to
...
output 2 more statistics, which are the mean absolute error and the standard
deviation of the absolute error. This means these functions now return 4D
rather than 2D vectors.
I also made test_regression_function() take a non-const reference to the
regression function so that DNN objects can be tested.

Changed the mean squared loss layers to return a loss that's the MSE, not

0.5*MSE. The only thing this effects is the logging messages that print during
training, which were confusing since the reported loss was half the size you

Made resizable_tensor objects not perform a reallocation if they are resized to
...
be smaller. Instead, they now behave like std::vector in that they just change
their nominal size but keep the same memory, only reallocating if they are
resized to something larger than their underlying memory block.
This change makes some uses of dlib faster, in particular, running networks on
a large set of images of differing sizes will now run faster since there won't
be any GPU reallocations, which are notoriously slow.

included in the edge graph. If it isn't then the output labels from

that doesn't include labels for all the inputs.
