- dynamic label values instead of ConstLabels
- use dto.Metric to gain histrogram value in exporter_test
- remove hash calculations

Move mapper to a package 
This allows the mapping logic and configuration format to be re-used by
the graphite exporter.

0ac908603a Update documentation of metric name escaping. 
The escaping changed in 728bdc52ae, before
0.1.0. Add a test for the escape function, and test various cases,
including those mentioned in the README.

This reveals that the README is inaccurate, adjust it to what has been
the reality for many years. Fixes #97.

ea77554dc4 Force IPv4 for the mock TCP listener. 
Travis CI [does not have IPv6][0] in any environment. It could be
[enabled][1] if we ran the build in a VM, but that is much slower to
start. Instead, we just force the test connection to use IPv4.

494cc38bf8 Don't panic when negative number counter is submitted. 
Instead now we will send a warning message to the logs
and continue on with our day.

Also a guard has been added when we detect a channel has been
closed and the `Exporter.Listen` function will return out of
its loop vs always running. When a channel is closed there will
be no more data to consume, so this seems correct. It also allows
for a test to be written for the panic.
