Detailed Description

The actual UTM conversion processing takes place in this helper class, which is a singleton due to the large memory footprint of the underlying PROJ.4 projections library structures.

Thread safety is enforced with mutexes around the PROJ.4 functions, but could be achieved in the future with a thread-safe version of PROJ.4 or ignored all together if the calls can be determined to be thread safe in this context.
