* fix find_min_global finding wrong answers
Previously, find_min_global would produce wrong output when passed
a collection of initial evaluations because the solver expected the
y-values to be multiplied by -1. This fix does that when minimizing.

that cuda is available even though it knows it didn't find cublas, which
is part of the standard cuda install. So we need to add a check to see
if cmake *really for realz* found cuda.
* Added exponential distribution
* tab problem removed?
* forgot std::
* Also added Weibull distribution. Very useful indeed.
* Simple Weibull distribution unit test
* don't forget std::
* sorry, typo
* [RAND] - seed the random number generators for consistency and no nasty surprises
- added parameter for tolerance
- added unit test for exponential distribution
* [RAND] print the spinner more often
* [RAND] up the tolerance for kurtosis a bit
* [RAND] refactored parameters to reflect documentation on wikipedia.
* [RAND] added documentation to _abstract
* [RAND] i switched the order of the arguments to get_random_weibull and didn't update the unit tests. oops

* fix typos
* add cifar-10
* open files in binary mode
* print messages with file name only, like mnist loader
* some fixes
* add mnist.cpp to CMakeLists.txt
* fix test index
* do not use iterator in cast
* add cifar.cpp to all
* Add Davis' suggestions
* no need to use namespace std and clean up empty lines
* [SERIALIZATION] fixed bug when (de)serializing vector<complex<float>>. DLIB_DEFINE... macro uses __out and __in variables names for ostream and istream objects respectively to avoid member variable name conflicts.
* Refactoring objects in DLIB_DEFINE_DEFAULT_SERIALIZATION to avoid name conflicts with user types
* Refactoring objects in DLIB_DEFINE_DEFAULT_SERIALIZATION to avoid name conflicts with user types
* removed tabs
* removed more tabs

* [DLIB] extended proxy objects to work with strinstream, istringstream, ostringstream and vector<char>
* [DLIB] - use std::istream and std::ostream instead of std::istringstream, std::ostringstream and std::stringstream.
- put back the filename member variable for better error messages
* [DLIB] - review requirement

* [DLIB] added seekpos and seekoff functions. These are necessary for functions in iostream base class to work properly. e.g. seekg. Note that in seekoff, you do NOT want to check the validity of read_pos after it has been updated. dlib::vectorstream and std::iostream work together to set EOF and/or badbit. Doing something like seekg(10000) should not throw even if the underlying buffer has 2 bytes. You should check if EOF is set and possibly call clear(). We have removed seekg from dlib::vectorstream as this adds confusion. Now std::iostream::seekg is called which somewhere down the callstack will call seekpos and/or seekoff. So there should be no diverging functionality between calling seekg on dlib::vectorstream& or std::iostream& when there is a cast.
* [DLIB] vectorstream unit test is updated to run identical tests on dlib::vectorstream& and std::iostream&
* [DLIB] only support read pointers and delete copy and move semantics
* [DLIB] explicit tests for seekg() in different directions
* [DLIB] - no need to delete the move constructor and move assign operator. This is implicitly done by deleting the copy constructor and copy assign operator.
* [DLIB] - remove leftover comments. no need
- use more idiomatic notation
