472f5d9020 Add TFloat data type for neural network 
Up to now Tesseract used double for training and recognition
with "best" models.

This commit replaces double by a new data type TFloat which
is double by default, but float if FAST_FLOAT is defined.

Ideally this should allow faster training.

edd599fa7b Replace more GenericVector by std::vector and remove GenericVector::choose_nth_item 
KDVector is now derived from std::vector.

This requires an update for unittest nthitem_test because
std::nth_element does not handle all corner cases of choose_nth_item.

c12dde2862 Use float instead of double for learning_rate, momentum and adam_beta 
Only WeightMatrix::Update used double parameters, all other functions
already used float. So this change avoids unnecessary conversions.
