cam: options: Create a template class for options

Browse source 
In preparation to adding more parsers create a template class to hold
the parsed information. The rational for making it a template are that
different parsers can index the options using different data types.

The OptionsParser index its options using an int while the upcoming
KeyValyeParser will index its options using strings for example.
