Add more concurrent chained map implementations

There are really only a few different types of implementations
that we need to consider:
 - primitive mapped keys
 - primitive (+number) mapped values
 - reference vs object mapped key/values

However, if we want keys/values to have the following types:
 - reference
 - object
 - int
 - long

Then we need 16 map implementations.
This is unacceptable maintenance burden for maintaining what
is truly only one map implementation with a small set of changes.

To address this problem, we now have the capability of generating
source files from a template file.

Please see templates/template_spec.txt for details.

Using the template system, we can generate all map implementations
from one template file.
