eval function bug

[KennellyT]

I recently installed and began to use cymetrics. I tried to receive the "ReactorEvents" metric from my database 'db'. After using the eval function cym.eval('ReactorEvents', db) to receive the 'ReactorEvents' data, this error occurred.

cym.eval('ReactorEvents', db)
Traceback (most recent call last):

File "", line 1, in
cym.eval('ReactorEvents', db)

File "/home/tyler/anaconda3/lib/python3.6/site-packages/cymetric/evaluator.py", line 83, in eval
return e.eval(str(metric), conds=conds)

File "/home/tyler/anaconda3/lib/python3.6/site-packages/cymetric/evaluator.py", line 55, in eval
m = self.get_metric(metric)

File "/home/tyler/anaconda3/lib/python3.6/site-packages/cymetric/evaluator.py", line 47, in get_metric
self.metrics[metric] = METRIC_REGISTRYmetric

KeyError: 'ReactorEvents'
