History
Stefan Weil 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.
