This method attaches to a processor (Stretch Board), and uses the content of the Cap File, to
load the processor with some code. It typically fails for missing Cap File, Missing processor
code, or missing FPGA files.

This method provides access to the values in the cap file which opened this processor. The
values are returned as a Variant, so that string, float, and int values are supported by the
method. There is no write method. Cap files are read only.
