### global_properties() can not be specified up to subrecipe level
### which means catalogue mechanism names can not collide

Stupid float implementation from uint8
import numpy as np
def to_float32(exponent, significand):
assert exponent.dtype == np.uint8
assert significand.dtype == np.uint8
negative = ((exponent & 128) >> 7) == 1
exponent = (exponent & 127).astype(float)-64
value = 2.0**exponent * (1.0 + significand.astype(float) / 256.0)
value[negative] *= -1
return value

Automatically save all matplotlib plots to a database
'''
Automatically saves all you matplotlib plot using pickle to a sqlite database
such that you can open them later, interactively.
Put this file somewhere on your PYTHONPATH and add this to your .bashrc
